I'm not a vegetarian. I'm not the complete opposite, but if I had to choose, a nice steak, a leg of lamb, or even a nice and healthy plain chicken breast would top an all-veggie meal for me.
I was taken here by my girlfriend, a couple of years ago, an ex-vegetarian. I tried to be open-minded, but this was my experience, as I recall it..
Atmosphere: None. It's cramped, crowded, loud, and bustling. It's kind of nice if you're a people watcher, or enjoy a really upbeat setting, but I prefer my dining experiences to be more tranquil and relaxed.
Service: Service was passable, but these people just struck me as... snobby. They weren't terribly polite and took great pride in telling me the virtues of vegetables, as if I was ignorant.
Food: For vegetarian food, it was passable, but without meat, and without many of the more contemporary fixings of a meal, I could not shake the feeling that I was scarfing down a meal of "health food". Too much tofu (bland at that) and a lot of bean sprouts. It was well prepared, for what it was, but I don't find re-fried vegetables and nothing else to be terribly exciting.
I'm sure Vancouver's numerous hippies love this, but for a non-vegetarian, I really have nothing to recommend about this place - simply having a vegetarian salad at any other restaurant would give you a similar culinary experience, without the busy-ness and noise.
