The patio at OHSO is the best! Even on a hot afternoon, the misters, fans, and umbrellas kept us cool. Dogs are welcome on the patio, and they even provide little water dishes for your furry friends. There's a bike entrance from the crosscut canal, so people can walk or bike in on the canal path and enter from the back.
Service is exceptionally friendly, and there is a great brunch deal (buy a $10-15 entree and get a local beer to go with it). The beer is really great as well. On the downside, the food isn't super exciting. I've had the veggie burger and avo toast, neither of which were bad but just not mind blowing. In general, the food is typical bar fare.
Come for the atmosphere and beer, and have a great time on the patio!
