Lulu's has two things going for it: it's cheap, and it's close to Carnegie Mellon's campus. Besides that, the service isn't great, they have forgotten my food, and the food isn't that great. I keep going back because up until recently, there wasn't any other choice that close to campus for quick Asian food.
The items are hit or miss, and lackluster. Good luck. I'm not saying it's horrible, it's just uninspired, boring, and not that flavorful.
