50's is a huge amount of fun, if you get a good server. It's unique among restaurants because even in a city the size of Houston, we have nothing else like it. You can get good Italian food anywhere. Frankly, I'd rather go to Olive Garden or Carrabba's than MM.
In October, we had cousin Jimmy serving, and it was one of the highlights of our trip. We left with wonderful memories, and tipped extra.
