I'm a big Mad Mex fan, and have been to almost all of their locations surprisingly. We occasionally make it out to the Monroeville location when we meet with family. As such, we were here for Mother's Day to take part of their specials for the day.
The deal itself was great, $15 for an app, entree and dessert*. Why the asterisk? Well, the email from Big Burrito Group said "ANY" dessert, while this location said you only get the Mexican Brownie. All the desserts costs the same, so not sure why it mattered much. By the time we got to dessert they were out of brownies and we were able to choose a different option.
Overall, the meal fell flat on a lot of fronts... long wait times for drinks, they kept forgetting items we ordered, forgot sauce on the enchiladas, cold quesadilla, etc. And when the dessert came, well they were missing ingredients (like no ice cream in the ice cream burrito).
I think it was a great promotion, but either they were overwhelmed and/or just had a bad day.
