Does anyone know of a good, upscale sushi restaurant?

Preferably a relatively fancy place within the walking distance of a romantic spot with some veiws. I realize that's probably too many conditions, lol, but I'm looking for somewhere to go for our first wedding anniversary!

Or if anyone has other ideas for a nice romantic dinner that would be great too! This will be one of few nights we have away from our baby for the foreseeable future.
