Went to Thahn Long on the suggestion of a friend who raved about the roasted crab. He was right on about that ... I had the drunken crab and it was outstanding! Also tried the roasted calamari and this was very tasty as well. As many other reviewers have noted Thanh Long is a bit pricey, but well worth it.
My only concern was parking. I drove around the neighborhood for 15 minutes before finding a spot on the street. Just something to keep in mind when you visit.
