Came with my Grandma to eat some authentic Northern Chinese food. She can certify that this is certainly Northern food with a mix of Shanghainese (Xiao Long Baos). We ordered:
Fried dough (yui tao) dipped in sweet soy milk
fried dumplings
xiao long baos
fried buns
some red bean rice cake thing for the dessert
stir fried greens
Everything was delicious, especially the Xiao Long Baos! Would pass on the red bean rice cake, wasn't anything special. Also, if you're counting calories I would avoid here because they use a lot of oil (especially for the greens). But fat is flavour!
