There is only one reason to bother coming to Chin's: the cream cheese puffs.
If you get anything else, you're wasting your money. I'm not saying this because "It's not authentic Asian!"--I'm saying this because the flavors are generally bland, the food is generally overcooked (or has been every time I've been here), and the food tastes real bland and repetitive after the third bite.
Otherwise, as others have mentioned, you can get better American-Chinese elsewhere and for cheaper. But if you want the real-deal kind of Asian food, Fugu is the one. Normally, I wouldn't suggest going to other places, but Chin's is such a rip-off compared to other places.
However, I will say this: Chin's has a very neat ambiance and the setting itself is much nicer than any of the other Asian food places on or near State St.
