I had a hard time getting used to mushrooms, oatmeal, macaroni and cheese, and fried eggs. Mushrooms took me until I was 28. The others were sooner, though none during the same year.
I may try mole again, but not for a while. I'll wait till I get to LV. They might do it different there, who knows.
Those are all things I liked the first time. You probably won't find any different mole in Las Vegas; it's a Mexican dish, so Mexican cooks make it roughly the same way.
