When it comes to dog-friendly restaurants, O.H.S.O. takes the phrase to a new level. Lots of places will tolerate your four-legged friend, but few (if any) make your pooch feel as welcome as this Arcadia spot, the original O.H.S.O. location. Dog owners and their canines are openly encouraged to dine and drink on the restaurant's spacious back patio, which even features booths equipped with carabiners for your pet's leash. The décor also shows how much this place loves your pet, with framed photos of smiling pups covering much of the outdoor wall space. What's more, every four-legged guest gets a bowl of water and a free dog treat, which are made with spent grain from the brewing process. We particularly love bringing our furry children to hang out during Sunday brunch, when we've seen as many as a dozen dogs of all sizes enjoying the scene.
