A bunch of my Chinese friends alerted me to a branch of this is a large hotpot chain in China that has just surfaced in Quincy, MA.
You might be able to find better scallion pancake/cong1 you2 bing3 in other parts of the world, but it's one of the best in the greater Boston area -- good balance of crisp outside and a pleasantly chewy layer within. Ditto for seseame crusted shao1 bing3/sesame pancake, a nice nuance of salt in this thicker multi-layered wheat based pancake.
Broths for the hotpot are well flavoured, complex, aromatic. The sichuan style umbing spicy/ ma1 la4 broth is not as fiery as it can be, but there's no holding back on other flavours. Had less of the black chicken/wu1 ji1 broth broth but there was a reasonable depth in the flavours. About as good as it gets in the Boston area.
We order huge amounts of fatty lamb and the special cut of lamb (just called lamb slices o the menu. Great stuff, good flavour, sliced to a right thinness. Nice quality of meats and vegetables too. Flounder fillets were clean tasting and fresh. taro's a good order, especially for soaking up the broth, as are the cellophone noodles. Fried gluten balls wuxi style are stuffed with little dab of minced meat and also worth trying.
Cold appetizers are well made: dense strings of chilled dried bean curd, jellyfishcut to a moderate thickness, bright coloured slivers of vegetables seasons lightly with sesame oil in the Mongollian Fresh 18.
Inexpensive and definitely worth going if you live in the greater Boston area.
