The Wasabi sushi bar is open at 1228 Washington Ave. Despite the uninspired name, the sushi is excellent. The atmosphere is great, too, especially the chef's enthusiastic greetings and farewells to guests from the bar in back. The maki rolls are small, but the bento boxes are gigantic. I'm dying to camp at the bar one of these nights and order the Sushi Okonomi: "You eat much as you can, what ever you want."
They've got great lunch specials, so check them out if you work downtown. If you live or party down here, you can presumably afford dinner, with prices more in line with the quality.
