He's basically me, so barring anything sexually oriented (because I honestly can't think of anything that tastes better than cum)... Hm. See, I haven't got as many choices as others. I don't eat red meat or poultry. Tried to give up fish, failed, so I still eat that. :3
Definitely sushi, though. Eel. Strong taste... served warm unlike other sushi because eel is generally cooked beforehand... mmm... Of course it has to be made right. Not counting sushi, because it is by definition instant win... shark. Shark is quite good. Has anyone ever tried it? Like a cross between fish and chicken.
To drink... hm. Why haven't I tried vodka yet? O.O I have to try it sometime. Vodka sounds good. *murrs, then coughs* Anyway... things legal for him to purchase, energy drinks. You know, Monster, Rock Star... they have that burning sensation. Or alcohol based mouthwash, which has a similar burning sensation from the alcohol. Yum.

Things that he can't buy... definitely wine. Again, I must stress that vodka sounds good but I've never tried it.
