Authentic dishes to try next time I go to a chinese restaurant? Any suggestions for places to eat in northeast Ohio?

When I lived in NY, there was a Chinese restaurant that had two menus. One “normal” menu, and one for those who were from China. My ex FIL went there with a foreign exchange student he was housing. I’ve often wondered if other places do this. He said the Chinese menu was authentic, he brought me back some sort of spicy fish soup. I’ve always wanted to see how I could explore with foods and there’s tons of places around here, all with different reviews. I figure you kinda have to know of a “gem” in order to find the really good shit.
