Piranha killer sushi is a small chain (3 locations, 2 in arlington and one in ft worth). It has far and away the best creative, fun, and tasty rolls we have ever had, anywhere. Nobu, kenichi, Tei Tei, Yutaka, dont hold a candle. The chefs combine everything from mulitple sauces, fruit, and very fresh fish (cooked and raw) with aplomb and style. It seemed every roll had at least 3 distinct flavors and 3 distinct textures. The "marry me" and sinister rolls were standouts. Prices are reasonable, especially for the size of the rolls (typically double a normal roll).
Chicken dishes (and rolls) were also great. There are also several desserts--chocolate tower, fried ice cream with dark chocolate and raspberry sauces, and fried bananas ala mode-- that were terrific tasting, large, and fairly priced.
The closest location to us is almost 20 miles and we will make it a regular stop.
