If you want good, quality Chinese food in the South Shore, Beijing House is the one to beat. I have eaten there dozens of times over quite a few years, and I really appreciate the large menu, strong complementary oolong tea, and the kind staff. I have never eaten their buffet (and wouldn't as I prefer food cooked to order) or their sushi (I go to Japanese restaurants for that), so my review is only of their core Chinese menu. As a recommendation, their sesame tofu/beef is really top-notch, although it doesn't hold up well as take-out. I stick to it for dining in, but order several other things when I want take-out. Overall, though, I highly recommend this place for lunch or dinner. I will certainly keep up my regular visits there!
