Go figure. The night my husband and I brought our 5 pound yorkie and 12 pound weenie dog to the Dog Bar...there's a GREAT DANE meetup group.
Besides the fact our doggies were intimidated to death, and didn't move around too much (would YOU move around and wag your tail if you were 5 pounds and the place was taken over by 160 pound GREAT DANES??) we wanted to like the Dog Bar. It just didn't gel for us.
In the end, we found it a bit unclean and the service was kind of, uh, not there. None of the dogs were asked if they had their rabies vaccines like they should be.
It's a great concept...simple b/c you can bring your own food, and it's a relaxed setting...but again, something about drinking around wet pee spots of gravel and poo didn't sit right with me.
