Probably the only good eat-in Chinese restaurant on the west side of Madison (they're actually in Middleton). In contrast to some reviews, we've always found their service to be friendly and attentive (I think the owner has been there every time we've gone). While they do have an "authentic" menu (in addition to "Americanized Chinese"), I think the "authentic" menu is still pretty tamed down, especially with respect to spiciness. That said, my wife and kids are probably less of a fan than I am for the spicy stuff, so this place pretty much fits the bill for everyone.
We've also had no problems with service being slow (and with two kids, that would be an immediate deal-breaker!)
