Its great because its what american chinese food is supposed to be. Quick, cheap, dirty, and delicious! Great portions, great price. It'll fill you up, have no fear.
My personal favorite is to get the sesame chicken, and have a friend get the chicken with veggies. Then you kinda mix the two together so you get a little veggie, and a little sesame chicken. Your free "sides" include lots of fried or steamed rice AND a great egg roll.
Its not health food by any stretch, but its less greasy than other places (the right amount of grease in my book).
