i actually had it when i was in beijing but i'm not 100% sure if it was the real authentic style. it was a vacation tour and they usually take you to restaurants that are somewhat westernized...
if i'm not mistaken....we had "3 eats" at shanghai river....one was using bones for soup, one skin and one cabbage.....part of a set dinner menu i think.....tasted good but waited FOREVER for each course....not worth the wait...
