We've eaten at San Angel Inn on three seperate occasions and had bad service and bad food all three times.
The first time I ate there (Jan '05) was with my elder son and GD. None of us ate more than a bite or two and finally my then 8 y/o GD asked if we could leave and go somewhere else to eat. When we finally found someone to go find our waiter who had been absent since bringing our food, he didn't even ask why our plates were vitually untouched. He just handed us the bill.
Sept '05 my younger son and D-I-L couldn't believe it could be that bad and wanted to try it. We were on the
DDP, but no way was I going to waste a credit on a meal I knew I wouldn't eat. I asked to order the fundido and use my DDE card to pay for my meal. I was told I couldn't use my DDE card because my son and D-I-L were using their DDP and two discounts could not be used at one table. We had been using both all week with no problem, A manager was called and she also refused to let me use my DDE card for my meal. I said fine, then my D-I-L and I will share a TS then. Again the food was inedible and we left our food almost untouched. Again when we asked for our ticket the waiter didn't even ask why we didn't eat more than a bite or two.
Last Sept my mom wanted to try it despite both my sons telling her how bad it was. We decided to try if for lunch to see if it was any better. NOPE!! My mom is a very brittle diabetic and without thinking ordered something that had mole in it. I immediately let her know that mole had chocolate in it and she couldn't have it. The waitress corrected me and said their mole was not sweetened and would be fine for a diabetic. Huh? I'm from Texas and know Mexican food--mole is sweet. The waitress assured us again that theirs was not. Sure enough, my mom took one bite and almost choked, it was so sweet. We waved the waitress over and her only response as she started to walk away was "Oh, sorry. I must have been wrong". No duh, we asked for something else and was told she would have to use another TS credit. We asked for a manager, explained what had happened and was asked "If you knew it was sweet, why did you order it". Maybe, because your waitress assured us it wasn't sweet. He rolled his eye and just walked away. We again left without eating.
No way would I enter that place again. We knew going in that it wasn't TexMex, but here in east Texas we enjoy authentic Mexican food as well as TexMex and the food we had all three times was just not prepared well. All three times it was either cold or barely lukewarm and twice the black beans had a scorched taste. Chips looked like they came out of a bag and the hot sauce out of a jar.
I'm sorry to hear about your bad experience. I was there the same friday night for dinner at 8:00. We were seated in 5 minutes and loved the service and the dinner. I would definitely go back again
