Mikuni for California/American style sushi. Hands down the BEST and freshest sushi in town.
Nation wide freezer meats downtown on H for the best cheese burger in town (no joke, but its a little pricey because they use all Harris Ranch beef)
Squeeze Inn gets the #2 on burgers (power Inn).
Bud's Buffet on 10th for the best roastbeef/pastrami in town (trust me, I eat here 2 times a week and there is always a line out the door)
Chicago Fire in Folsom or Downtown for deep dish pizza (destroys Zelda's all day).
Paezano's (sp?) is good for Italian.
I could name a bunch more because I am always on the quest for the best foods in Sac, but keep in mind most of the places I named do not have the same ambience as Bandera, Ruth's or Morton's, however the food is killer.
