This is like probably the best food-court style restaurant I've ever been to, short of those of some corporate cafeterias on the west coast. The food is cheap, delicious and comes in decent portions. Like not amazingly delicious, but tasty enough that I wouldn't mind coming once or twice a week had I not been on a stricter diet. On top of everything, they're clean and quick. It's like some enlightened Asian McDonalds.
The sandwiches are the mainstays of their menu, but I particularly also enjoy the sides. The meatballs are cheap, probably possess a decent amount of protein and taste great (though some of my friends don't like them). They also have some drinks; bubble tea or other jelly type drinks.
