Well, as far as favorite drinks go, I'm basically a soda addict (dark sodas actually, I really don't care too much for the clear ones as they go flat rather quickly). I'm fond of the Coca-Cola Classic, but I also like that Cherry Dr. Pepper.
I'm also a chocoholic, I don't have to have it every day but I usually like to have something chocolate in the house for those moments when I need a choco fix.
Food-wise, I really love seafood. Fish, shrimp, lobster, crab...good stuff. I don't care much for clams or salmon, though. Sadly, since I'm really the only person I know who loves seafood, I don't get the opportunity to go to a lot of restaurants that specialize in it, as I don't really go do restaurants by myself. There's a lot of seafood I haven't tried yet and would like to (shark, for example, I have heard is very good).
Probably because of my (half) Mexican heritage, I'm also fond of good, homemade Mexican cooking. That is the one thing I miss most about living in L.A., there is a ton of great Mexican food places to eat there. The town where I live has Mexican restaurants too, but I have found them to be rather bland or just not very good. I'd say my favorite dish are tamales; they are the perfect food because you can eat them at anytime, with anything.
And yes, I also like shepard's pie.
