This update is in regards to Mad Mex at the Robinson Township location, specifically going with a larger group of people:
I most frequently visit Mad Mex at this location and being that it is at the crux of roads between where I live and other family lives, I have gone here a few times with a bigger group of guests. After my most recent visit I would not suggest that is a good plan.
The most recent visit with a group was on a mid-weekday night with no special game playing on the screens. However, the place was really packed. Our plans had been completely last minute, so we didn't get to call in a reservation. We were told the wait would be 20-25 minutes; we waited about 50 to an hour to get seated. Service does take longer for big groups but it was so slow about 2 hours passed from when we were seated to when we were able to pay the check and go. The evening included our server who spilled the whole tray of drinks on our table (hey, it happens) and who eventually became either so stressed or annoyed that she didn't tend to our table for long periods of time and when she did so she was not very polite.
Another warning for going with larger groups is in regards to ordering dessert. We had a few kids with our group and so ordered the brownie a la mode and a couple of ice cream burritos. All of the ice cream was melted for all three dishes when it arrived. It was as unappealing as it sounds (think: soupy cream burrito) but we were all so eager to leave that we didn't bother to mention it. Melted ice cream at restaurants usually happens if the plates come straight from the hot wash or--as it appeared in our case being that the plates weren't hot--the server waited too long to pick up the dessert after ordering it through the P.O.S.
I can most accurately describe the entire experience that evening as arduous. Though I enjoyed the guests that I went with--this time being my family--the atmosphere of stress and negativity was set by the service and pacing of the meal. I was quite relieved when we left and was wishing in hindsight that we had gone anywhere else. It will be awhile before I can go back again, but it definitely won't be with a group of more than four.
