Charleston (SC) - tapas, small plates
Chai's, right next door to Basil and owned by the same folks, is my favorite tapas place downtown. The menu is all over the place but many of the dishes display an Asian influence. Great SE Asian salads like green mango salad and green papaya salad.
Raval, just down the street, is also pretty good. Much more traditional tapas prepared in a tiny kitchen.
Not downtown, but getting great reviews, is Soif, located in the I'on neighborhood of Mt. Pleasant (so just over the bridge). I haven't been yet, but everything I hear sounds promising.
And if I remember correctly, doesn't SNOB serve small dishes--not tapas sized but smaller than their regular entrees?
