Met friends here for a late lunch. The food was good but not great. Reuben sandwich was filled with corned beef on good bread. The waitress was fairly pleasant, but generally inattentive; she never refilled my water glass and only came to our table when signaled.
The bar/dining area seemed clean overall, but a trip to the restroom revealed a dirty hallway floor and unkept ladies room.
Tavern In the Wall is an OK place, but nothing special. I doubt that we will go here again.
