Anything located in Treasure Island kind of makes me question as to how fabulous it will actually be, but I was so pleasantly suprised by Social House. This is your typical trendy sushi restaurant, but the food is still quite good. As someone else mentiones, not a fabulous as Tao, but something I still highly recommend.
Definitely has some cool ambiance. If you're looking for a trendy, hipster restaurant, you've found a place.
