Misushi is located where the ill-fated Mr. Papas/Potato-Head clone used to be and actually offers tasty sushi and japanese cooked items like yakitori and some kinds of teppan-yaki-ish stuff too.
The problem here is the time it takes to get your order; I would suggest that upon arriving at the Gran Plaza, order your sushi platters, go take in a movie and when you're finished, your sushi will be ready.
OK it's not that bad, but almost. If you're in a hurry or starving don't consider it. I recommend the california rolls and also the Misushi roll, both of which are quite good and reasonably priced. You can ask for regular soya sauce instead of that lemon-diluted stuff they give you. Chopsticks are not always available, though and somehow sushi with a plastic fork doesn't really seem authentic...
