Fuck this place.
A few months back I placed an order in store and watched them make it. They made it wrong, putting items I am allergic to in the order. They caught it and said "oh, pick that out" and then tried to give it to me. I immediately asked for a refund. I contacted corporate about this and they never replied.
A few months later I tried to give them another chance. I went through the drive thru this time, ordered a combo and a couple of additional tacos. They didn't include the fries with the combo, which I caught at the drive thru window. When I pulled up to check my order it was, again, wrong. I went inside and got another refund. They seemed to be a bit confused as to what to do regarding a refund when I paid with a gift card but eventually just gave me cash.
It's clear that if you want to specify anything about your order (no tomatoes, extra lettuce, whatever...) or are allergic to something, this place absolutely does not care. Corporate also does not care if you have any sort of issue either.
