I like OHSO a lot! It's not the best place to eat as the food is not the best and it's a bit expensive for what you get. However, I don't go to OHSO to eat...I go there to drink on the patio! The patio is very dog friendly and it's one of the better patios in Phoenix. They have a good list of local beers, craft beers, and mixed drinks. This is a nice place to meet with a group of friends and hang out for a while.
I also appreciate how accommodating the staff has been. I went there to watch the presidential debate and the staff was very willing to put the debate on for me. I had already gone to a few other places and they refused to do it--so I really appreciated OHSO's flexibility on the manner.
Bring your dog, a few friends, and go enjoy a drink on their patio.
