Two Sushi bars in La Jolla on Prospect...
Just walking past them and the stench they emitted for half a block made me nauseous.
If it were only rice...I'd be ok with it. Tom's right, raw fish is the fastest way to catch a bottom feeding disease.
I avoid sushi for the same reason I avoid shrimp - which also feed on fish excrement.

(After enough lifetimes stuck on a tiny island with only fish to eat - it's hard to pretend it's a delicacy! Personally, I nuke my fish and avoid salads I haven't prepared myself.)
