For me sushis is the best food ever: you can eat it as you want without getting fat.

Even if you dont like raw fish, you can eat sushis with concomber or others vegetables, omelets, etc.

The only negative point is that it is very expensive and you need to eat it very fresh!!!

This doesn't immediately pop into mind, and I don't think I've ever done sushi drunk. However, it probably wouldn't be a bad drunk meal. When I think of drunk eating though, I think of getting as much food for as little a price as possible. Sushi just doesn't seem to fit that model.

Am I puking because I drank too much or because I just ate raw fish?

Until recently, I'd have rated this a one, but a sushi place opened next door to one of my favourite watering holes that sells a hand held California roll for about a buck. Makes for great belly fodder on the way home.
