01 | Overview
What is Green House?
Green House is a Korean restaurant in Argentina that operates exclusively as a pickup service. They have no online menu or ordering system, so customers have to call in to check dishes, prices, and place orders. I designed a mobile app to simplify that process, from browsing the menu to coordinating group orders.
02 | Problem & goals
Friction when placing orders
The restaurant currently lacks an online menu and ordering system, forcing customers to call to ask about dishes and prices and place orders, which makes the process lengthy and complicated.
The main objective of this project was to create an app that would facilitate communication between the restaurant and its customers while simplifying the current ordering process.
03 | Research
Understanding the landscape
In addition to a competitive audit, I also interviewed four people.
Key pain points:
Difficulty placing large group orders efficiently
Challenges in identifying suitable dishes for people with dietary restrictions
Difficulty determining the optimal pick-up time
04 | Design
From insights to ideas
Based on the research, my initial design focused on providing the following:
Full, easy access to the menu
Support group orders
Clearly communicate dietary restrictions/ allergents
Pick-up scheduling
I started by sketching multiple paper wireframes. Next, I selected the elements that best addressed user pain points and created a low-fidelity digital wireframe and prototype.

Testing the first draft
Tested the low-fi prototype with five users and found that:
Users were confused about how the group ordering feature works
Some had difficulty spotting the dietary/allenrent tags
Users wanted a cash payment option, a common payment method in Argentina
Some users wanted the option to pay in full or split the bill
06 | Design
Refining the experience
Based on the feedback, some of the new implementations included:
Added context surrounding the group ordering function to increase clarity
Increased visibility for dietary tags
Option to pay in full or split the bill
Cash payment method
07 | Evaluate
Testing the second draft
The following insights were found through testing with five users.
Most users understood the group ordering feature and how it works
Users had difficulty understanding how to edit the ordering group
08| Design
Final app deliverable
I incorporated this last round of feedback into a finalized high-fidelity prototype, refining the group-editing flow for clarity.
09 | Reflection
Key Takeaways
I learned how to design for the unexpected. During User testing, users repeatedly interacted with the interface in unexpected ways. Each round pushed me to rethink my design to improve it, reinforcing the importance of testing and iterative design to build intuitive interfaces.
Good design has to account for the context in which it will be used. For example, adding a cash payment option for a restaurant app in Argentina.

Next Steps
More usability studies to identify additional areas for improvement.
Work closely with the restaurant to make it easy for them to update their profile, combos, and menu items
