Well, there are lots of foods that I don't like that lots of people don't like. That's not all that interesting. Like I can say I'm not very keen on Kiviak or century eggs or balut or casu marzu. But that's hardly surprising.
So I'll limit it to things other people seem to love.
I hate Pho. I dislike pudding cakes. I dislike cranberry juice (okay it seems to me that only women like this, they've conditioned themselves to drink it to fight utis) I dislike tequila a lot.
Food: Seafood. In general I dislike it very much with the only exception fish but even then it's really not my thing. Dessert: Anything overly chocolate like rich chocolate cake. It's too much for me. Drink: Diet Coke. It tastes really bad to me. Alcohol: Any kind of beer or whiskeys...
