LA PLAZA TAQUERIA

Mobile app research and design to make La Plaza’s food modern, accessible, and discoverable for the community.

January 2023 – July 2023

Summary

Challenge

From humble beginnings as a traditional taqueria in the back of a grocery store, La Plaza made a decision to flip their business model on it’s head. With the intention of bringing their food to their audience, they purchased a fleet of food trucks and rebranded into a traveling taqueria. With an outdated website and no way for customers to order food, they needed a digital presence that served their new business model.

La Plaza’s word-of-mouth reputation didn’t translate to the competitive food truck scene, where discovery happens online. Without a digital presence to share their authentic brand and reach new audiences, they risked being overlooked.

My Contributions

As a product designer, my job was to first conduct research to understand the target audience and the ways in which they currently engage with mobile ordering. The design solution centered around streamlining the ordering process which not only includes making selections and paying for them, but also being able to know where the food trucks are at any given moment, understanding wait times, order statuses, and coordinating pick-ups.

CASE STUDY


01
Introduction

Project Background

Authenticity is what people crave. Tacos are also what people crave. When a business that has a rich history of authenticity and community decides to do something daring, amazing opportunities start to reveal themselves.

I was part of a project to help a local grocery store taqueria make their mark in the food truck world. We designed a solution that not only allowed people to place and track mobile orders, but also found a way for the trucks themselves to be discoverable by the masses. 

The Client

From humble beginnings as a traditional taqueria in the back of a grocery store, La Plaza made a decision to flip their business model on it’s head. With the intention of bringing their food to their audience, they purchased a fleet of food trucks and rebranded into a traveling taqueria.

With an outdated website and no way for customers to order food, they needed a digital presence that served their new business model.

The Problem

La Plaza’s word-of-mouth reputation didn’t translate to the competitive food truck scene, where discovery happens online. Without a digital presence to share their authentic brand and reach new audiences, they risked being overlooked.

The core of the challenge was “to streamline the ordering process” which not only includes making selections and paying for them, but also being able to know where the food trucks are at any given moment, understanding wait times, order statuses, and coordinating pick-ups.

The Approach

Once I understood the challenge and what the client’s goals were, I mapped out a process of how I thought I could best achieve the outcome La Plaza was looking for.

Research

Initial Discovery

Before diving into design, I did some initial discovery by interviewing a handful of potential users. I wanted to better understand the target audience and the ways in which they currently engage with mobile ordering. My goal was to get a better picture of an ideal mobile ordering experience by understanding the best and worst parts of ordering food from these people’s point of view.

 

Research Goals:

  1. Understand frequency and motivation for mobile ordering.
  2. Identify what makes an ideal mobile ordering experience.
  3. Understand challenges or pain points within the mobile ordering experience.

Key Findings

After synthesizing my research results, 4 key finding surfaced as focus areas for the solution.

Time

Busy people lack the time to stand and wait in long lines for food.

“When my boss asks me to get lunch, I usually have about 30 minutes.” – Interviewee

Nutrition

It’s often difficult to access the nutrition information and know the health value of food from a food truck.

“When there’s no calorie count, I sometimes end up getting something unhealthy.” – Interviewee

Location

Food trucks can be hard to track, and it’s difficult to know which trucks are close by.

“I wish my favorite food truck had a tracker so I knew when it’s in my neighborhood.” – Interviewee

Format & Function

Menus can be wordy and contain no images, making it hard for a user to know what they are ordering.

“I love when I can see images of the food so I know what I’m buying.” – Interviewee

Persona Development

When looking across my research findings, two key personas took shape. The established professional, and the hopeful intern.

Reframing the Problem

How might we enable new audiences to find and engage with La Plaza online in ways that reflect its authentic brand?

User Journey Map

Mapping Jade’s current user journey for food truck order and pick-up helped me to identify some key pain points in the process and also improvement opportunities for a future solution, including some potential key features.

Potential Key Features

Food truck GPS tracking system.
Menus with large pictures and short descriptions.
Screen reader and translation feature.
Nutrition cards for all menu items.
An item favoriting system.
Online ordering with third party payment options.
Order tracking with live updates and notifications.

03
Ideation

User Flow

As a user, I want to locate a truck, place an order, pay for the order, and track when my order is ready to be picked up.

Sketches

I sketched at least 5 versions of each screen before I chose final layouts, ensuring I explored a range of possibilities before deciding on that I would bring to digital. The majority of the screens address at least 1 pain point from user research.

Initial Design Ideas

As I brought the designs into Figma, I worked to further flesh out screens based on all feedback and findings from the user research.

Truck Location

Users need to quickly and easily locate a truck.

Nutrition Info

Users want to see what they are ordering and know the health value of a menu item.

Review Screen

Users need flexible payment options and an accessible review screen.

Testing & Iteration

Usability Study

At this point the prototype felt ready to get into the hands of some users to be tested. I conducted moderated 1-on-1 usability studies with 5 participants where they were asked to complete a series of tasks and I observed their behavior. I wanted to understand the level of ease of navigating the app from start to finish and see if there were any points of confusion or places where people got stuck.

 

Research Goals:

  1. Understand how quickly and easily users are able to locate a truck nearby browse the menu and order food.
  2. See if users view the nutrition information for an item. 
  3. Find out if they find the order tracker/countdown useful.

KPI’s:

  • Time on Task
  • Conversion Rates
  • User Error Rates

Key Findings

After synthesizing and analyzing all of the user feedback, a few key findings surfaced.

The Map Icon is Not Obvious or Intuitive

Participants were unclear about what the icon on the map represented.

“It was easy to see the map icon, but I didn’t know if that was a truck or me” – User

The Nutrition Toggle is Not Immediately Discoverable

Participants took longer than expected to locate the nutrition toggle.

“It took me a minute to find the nutrition toggle because it was off to the side” – User

Some Users Want to Pay with Cash

Participants felt there should be a cash option in payments on the cart screen.

“Could there be a pay when you pick up option, like cash?” – User

Users Find the Route Function Extremely Useful, But Not
Easily Discoverable

Participants saw a high use for the route function, but most could not find it.

“The route is a great feature to not have to go hunt for, and have it load up on it’s own.” – User

Iterations Made Based on Feedback

Based on the key findings of the usability study, I updated specific areas of the app.

Map

The map icons weren’t obvious to users so I made them more literal to represent a person and a truck. I also added pull-up functionality to the truck list, giving the map more screen real estate due to it’s popularity with users.

Nutrition

Users experienced difficulty finding the nutrition information of a menu item so  I switched the toggle to an inline “see more” button.

Payment

Not everyone wants to save a card or use digital payment so adding a pay at pick-up option was necessary.

Route

To users, the route function is valuable and needs to be a primary function that is easily accessible and obvious to find.

Final Solution

Defining a Visual Style

Before fully bringing the screens into high-fidelity I needed to define a visual style that felt rooted in the brand and connected to it’s Mexican roots. I did some research into classic and also contemporary Spanish/Mexican graphic design. I also spent some time collecting interior shots from restaurants that felt authentic but modern.

Brand Translation

Armed with a vibe, it was time to start applying the look and feel to the screens.

Splash Screen

Opening with a graphic animation adds a moment of delight and further reinforces the brand.

Truck Colors

Aligning the color of the icon to the actual color of the truck maps helps reinforce which truck a user has selected IRL.

Taco Images

Free floating taco images keep the emphasis on the food and allow a user to visually see what they’re ordering.

Order Countdown

Countdown informs the user of food status while the graphic reinforces the brand and adds delight.

Final Mock-Ups & Prototype

Fully branded and updated flow with the La Plaza brand applied. Includes any additional UX improvements based on learnings.

Conclusion

Reflection

Designing for La Plaza was both exciting and challenging because there weren’t strong competitors doing this well—we had something of an open canvas to create a fresh, valuable experience. To shape the solution, I drew inspiration from ordering and discovery patterns in apps like Uber, Lyft, and Airbnb, blending familiarity with new ideas that fit La Plaza’s unique context. What stood out most was the importance of translating the emotional and practical parts of exploring local food into a digital space. By engaging users throughout the process, we were able to refine the designs and sharpen the ordering journey with each iteration, ensuring the digital experience felt as authentic and approachable as the real-world one.

Key Takeaway

The La Plaza project highlighted that designing digital experiences isn’t just about usability—it’s about capturing the heart of what makes the physical experience special. By blending proven interaction patterns with deep user context, I learned that the most successful solutions feel both intuitive and true to the brand’s authentic story.
