There was a brief time in my life when I was eating 'gourmet' Chinese food nearly everyday--the kind of Chinese served bejeweled with gold flakes and real flowers and spooned morsel by morsel onto your plate by an army of immaculate and efficient servers. Even though I regularly saw people drop more than my NYC rent on dinner for two at this particular London eatery I remember more than once thinking. . . I could get this dish, sans the bells and whistles but with all the taste, for a fraction of the price--if only I were back home in Chinatown.
While it's true that Asian cuisine in London consistently underwhelmed me, (sorry blokes British food is still nothing to write home about Jamie Oliver or no!) part of the truth is that NYC simply has an abundance of cheap, but tasty Chinese food--and Green Bo is above average for its price range.
The veggies are savoury and fresh, the sauces familiar, but somehow better than what you thought you knew. As others have pointed out, Green Bo excels at dim sum, packing their steamed goodies with generous amounts of homemade goodness. If you go for dumplings go earlier in the day, as they become overly dry and leathery by the time they get served in the evening (even so they're better than average). The rice, which must be ordered seperately, tends not to be of very good quality, the tea the usual Chinese dive brew, and the presentation is nonexistent. Service is also apathetic, but efficient. HOWEVER nobody really cares about these things, because they're too busy stuffing themselves full of Chinese dumplings.
Average (vegetarian) meal for two with beers and tip about $25-30
