Seablue is very tasty - I've enjoyed it on several occasions. I think it gets overlooked quite a bit due to it's surroundings ( Joel Robuchon, Craftsteak, Nobhill, etc. ).
I really enjoy the way the menu is set up so that you can sample quite a few of the dishes in one visit without overdoing it. The desserts are killer as well. Mina's desserts here ( and @ Michael Mina as well ) usually have a distinct hot/cold theme incorporated. I once had a take on a molten chocolate cake served paired with a sassafras ice cream/root beer float. Outstanding to say the least.
