Needs major work
It’s easy to select the products you want to buy. The payment system seems to work as expected. You can do some customizations well, others are confusing, others are impossible. I should be able to put buttermilk sauce on my taco if I want. I should be able to make a classic chicken with ground beef or pepper jack cheese. Can I add beans to a quesadilla? Not sure.
Finally there are major bugs that have been there since the beginning. If I build my order and back out for any reason (like checking which coupons are available), I have to start over from the very beginning. Choosing locations is a pain.
