I actually work in the same building as this place which is the only fast food restaurant I buy from in the small food court.
FOOD: Their food is great because of the cheap price! I don't mean the food tastes cheap either. You can get a big box of salad for $6 (tax included). Now what do they mean by salad? They mean any fresh fruits, vegetables, noodles, potatoes, tofu balls, stir fry etc. they have that day and they will pack it into your box. There's just no meat. If you want meat I would recommend getting a sandwich or their special of the day which ranges from: korean style chicken, beef, fried chicken, etc. All the food tastes decent and again you just can't beat that price.
Service: Not the friendliest bunch but they do have a long line of day time workers to feed. Super fast though.
All in all, I love this place and it's very affordable for the good quality food that they serve. Also they have $5 breakfast!
