It was the second time I've visited the Guu. The food is good, however the portions are oh so limited. I spent 45$ and came home hungry.
This is a good place to come for drinks with friends, but make sure you eat beforehand.
Staff are very friendly, and promptly take your order. Service is quite fast, just make sure you make reservations (they now take reservations), otherwise, you'll be waiting for over an hour.
Overall I enjoyed the experience, I just found them to be overpriced and they serve very tiny portions. So you won't get your bang for your buck!
