We are regulars at Sushi Box. What our family loves about it is the wide variety of creative vegetarian options. Beyond the usual avocado and kampyo rolls, they have ACE (avocado-cream cheese-egg [tamago]), asparagus, mushroom, etc., and any combination thereof. Tofu Don is also wonderful, and the Oshonokanomiyaki (not sure if I got that name quite right) is super-delicious at weekday lunch--with interesting sauce(s?) over the top. We're not the ones to report on the actual seafood sushi, but for vegetarians, this is hands down the best sushi option in Madison.
