I've eaten here probably half a dozen times as I live a few miles down the road. Every time I come, I wonder why I don't come more often. The staff is very friendly without being overbearing, and the owner seems to always be there at least for dinner service, he seemingly greets every patron too which I always appreciate.
I usually stick to the sushi menu, so I can't speak to the cooked menu items. The Green Catepillar is one of my favorites. I also always choose a "Surpise Me" roll, and I've never been disappointed. The sushi just literally makes up something on the spot and it's always something I've never seen before. All the rolls are $8-$10 and would easily be in the $14-$16 at other sushi restaurants in a 10 mile radius. They also offer amazing nigiri and sashimi, many for only $1 - and large portions.
They also often bring tempura-fried oreos to the table if you're a regular or especially friendly. I wouldn't care what the interior of this place looked like as good and as reasonably-priced as the food is, but it just adds a gold star that it is cute and funky.
