This place is pretty good... less the fact the owner ticked me off one time when she had an attitude attack so minus one star for that.
If you don't want to wait over 30 minutes for a bowl of rice, call ahead and order (but make sure you have the up to date version of the menu as the numbers are different). The place is small, and busy almost all the time. Their rice rolls are pretty darn good and not as greasy as dim sum restaurants might be - try the one with everything in it... forgot the name. The rice bowls comes in a pretty decent size; it's good for 2 people I'd say. Prices are decent too. It comes with a soup (no salt added) and small dish of veggies for the day.
For those not familiar with this plaza, though, there is actually another casserole restaurant in the same plaza that's been there longer, but less known for some reason. There's not as many options as this one but the quality is on par.
If you're a fan of rice and casseroles, do give this place a try (and don't forget to order ahead!)
