I've been here twice. The first time I spent a lot of money and the second time I had to line up for two hours in the cold before getting a seat. Even though it's loud and the seating is uncomfortable, I still love this place.
They have a wonderful atmosphere here. When we enter the whole staff will greet us and when we leave the whole staff says bye. The service is good considering the amount of people and the busyness of the restaurant.
The food is not a disappointment either! My favorite dish is the avocado with melted cheese on top (I think it's a seasonal item). My favorite drink is the bamboo drink (might also be a seasonal item).
I haven't tried the Guu on Bloor but I'm certain it's just as good.
This restaurant is a great example of how great service can keep a customer coming back even if the restaurant is a bit pricier and there is quite a long wait before getting seats.
Side note: there's a space underneath your chair where you can store your purse so you don't have to put it on the floor if you're sitting by the bar.
