I love Todai...go there whenever I get a chance. Usually the one in Woodland Hills but I started going there(well, the parents took me) starting back in the 1980's.

of course, doesn't affect me since I've been eating tomatoes the entire time... mwahahaha
No buffets, salad bars, etc. for me. I've seen WAY too many kids sneeze all over their hands and then touch the tongs for me to ever go through that again.
As for seafood specifically, I'm a total snob. If I'm not within 200 miles of the ocean, or at a HIGH class restaurant that can afford to fly it in fresh, the seafood is strictly off limits.
