One word: Brunch
Sure you could come here for HH on Fridays (as there are always a large number of cute single ladies here).
Sure you could come to dinner.
I just don't know why you would! O.H.S.O is a brunch place period. A top 2 Mimosa in the Valley without question!
Back Patio! Forget about it. INSANE!!!!
I used to come here when it was "Black Forrest Mil" bar for dancing, and now that it has been totally revamped, I come here for the amazing back patio they added and great beer selection, mostly local to the AZ area is a big plus for us local boys.
And now... a game for you to play!
Everytime to you go... Create an acryonym for O.H.S.O and leave it as tip. I've played this game on FourSquare for years, but since Yelp is so much more amazing, I have to bring the tradition over here as well...
Some previously made acronyms we've come up with are...
Obviosly Hot Sexy Occupants
Other Humans Steal Olives
Outlandish Hominids Sucky Oxygen
Owning Honest Shiny Oysters
Outlandish Hyper Sensitive Orks
Orangutangs Have Sweetened Oranges
Etc..
Please enjoy the acronym game here by leaving them as tips!
