I also have had issues with service and never returned. The last time, a year ago, we waited 45 minutes for an appetizer. When I complained, our waiter told us that the "computer had crashed" and my order hadn't been registered, though everybody else was getting their food. Then it took him another 25 minutes to get our appetizer, which was a cold plate.

While overall the food is very good, I don't think it's worth what they charge. Maybe they set their prices that high to create a certain environment, and the bad service is part of that vibe.

In the end, they suffer from the same bad attitude as Taqueria, with the aggravating factor that M&P is 20 times more expensive.
