Seafood and snails. I haven't had escargot but after trying just the snails I have no interest in trying escargot.
I can usually handle shrimp, sometimes. I was at an authentic Chinese restaurant and I was thinking wow this is so much better than the fare that we normally get, then they gave me a steamed shrimp bao and I had to fight not to spit it out at the table. Then came the steamed minced beef bao I think I almost cried at that point, the shrimp was worse but the beef wasn't good steamed.
