I don't know any other restaurant where I could possibly wait 2 hours for a table, start out my meal unbelievably pissed off, and be laughing and singing their praises by the end.
I don't know if it was the fun, communal atmosphere, delicious small plates, or the saki we drank out of a giant bamboo carafe, but it happened.
Guu is absolutely a great choice for dinner. Everything we ordered was delicious. But I HATE HATE HATE the 'no reservations' trend in this city. I would attempt it again at an 'off' time, but you won't catch me waiting 2 hours.
