Sushi Town Mira Mesa SD
This place is always busy for lunch. They serve their sushi rolls on the conveyor belt, and you can choose your plate as it goes around (Yellow $1.75, Green $2.25, Blue $2.75,Red $3.25,Black Plate $3.75 - all 3 pieces each). Other lunch items are served, other sushi rolls, teriyaki,etc.
Getting sushi rolls to go always make a great lunch. The sushi has great flavor and texture. I tried the salmon and tuna. Getting 3 pieces unables you to mix and match and gets a nice lunch under $10.
Sushi Town is tasty, fun, and affordable. :)
