The food taste is pretty good. Not as flavorful as Poké I've had elsewhere, but I suspect any "make your bowl" ones won't be able to match the marinade of prepared Poké.
The people there are friendly and helpful in picking out your bowl.
My biggest gripe is the food portions are way too small for the price. If you got more ingredients or prices were $3-4 cheaper I'd go back willingly. As it is, I'd pass at the current prices.
