Here's the deal, you walk in and there are plenty of employees, but they will tell you they can't take your order, only online. The website will then say it's having difficulty, so you ask again in store and they help you by telling you to use the app. Customers walk in and get turned away, one after the other as you sign up for an account in the app. Then you order your food, but be careful, there is no place to mark any allergies. Be creative when naming your order for pickup, something like GLUTEN FREE GRAHAM OR DIE , ANYTHING to grab their attention. Then after you have succesfully ordered your food in the app, you can watch them make it without interacting with you at all. If they disregard the allergy, ask them to remake it as you watch, like an ordinary customer interaction you sought for to begin with.
Edit: the name trick doesn't work. It disregarded my chosen pickup name and used the name from registering my chipotle account, exactly what I need. Awful
As a Vegan who also has a gluten sensitivity it's difficult to find places you can eat as well as trust. I feel Frontera is one of these places. Although there isn't a ton on the menu for me I hope they will add some vegan options in the near future and the lack of options is why I gave 4 stars but for most this should be a 5 star experience. I highly recommend getting their made to order right at your table guacamole it's amazing!
