This place is unbelievable. Bronwyn introduced me to it last year, and its now one of my top 5 places to eat.
The atmosphere is unlike anything you've ever witnessed. As soon as you enter, the entire staff (including the kitchen) erupts in Japanese at the top of their lungs, greeting your entrance. A host eagerly asks how many seats you need, and if there is a wait, they take down your phone number.
Drinks come first. We always order two big Sapporos (32 oz. for something like 8 bucks, so cheap) and a big bottle of hot sake (Geikkeikan). Then comes the fun! Guu boasts a large tapas-inspired menu, and every night there is also a different feature menu. It's best to order dishes in chunks of 2 or 3 at a time. Any more, and you find your table rammed with too many plates.
The feature menu starts to run out around 9 or 10 usually, so come before that if you want to try the daily sashimi (always delicious). Don't panic though, the standard menu offers many sashimi choices as well.
Finish the meal with green tea ice cream!
Getting the bill is never a scary ordeal either. It always arrives with a handful of frozen grapes (yum) and the bill is always less than you expect. It really is CHEAP to eat here.
Guu is a must try. Go tonight.
