Okay, I'll admit it, Kisaku isn't the "quickest" restaurant around. (That's the only reason I didn't give a full 5 stars.) You might have to wait for a table, but there's a reason for that, and that reason is because people know good sushi when they find it, and nobody wants to leave. If you're looking for some fast-food style, grab-n-go sushi, then get out of the way, head on down to Blue-C or some other "joint" and grab some hour-old fish off the fish train.
BUT - If you're prepared to enjoy some sushi like a gentleman (or lady, as the case may be), then Kisaku is a fine choice. There's hustle, there's bustle, there's an energy present, and the fish is prepared with care and presented with flourish. On the rare occasions that it's calm, there is a quiet, refined elegance to the interior, but when it's busy (as it often is), there is a kinetic feeling to Kisaku that makes the dining experience contagiously exciting. Itadakimasu!
Pros: Fine, fresh fish, contagious energy
Cons: Yeah, yeah, yeah, long waits sometimes.
