Chinese Delivery Downtown -Dinner

So I am a student who lives in Downtown...
Any body know of some authentic chinese food that i can get delivered? (especially at night time)

Im getting tired of the usual selection of chipotle and potbelly's and seek something new!

I've tried House of Fortune, and thought it was okay. All i tried was the chicken in black bean sauce(tasted fine, chicken was kinda rubbery), the general tso's chicken(Gwiv likes it a lot, mine suffered from the ride over and was soggy, also a little too vinegary for my tastes) and some crab rangoon(i like em sometimes, but these tasted like they had liquid smoke in them, weird). I have been getting Opart Thai lately. Its not chinese, but its good, especially for delivery. I've tried the crying tiger beef(really good and smokey), the grilled pork appetizer(forget the name, but very good), and also the sweet potato and chicken curry(the spicier, the better but it can get very hot, if you ask).

heres a thread about it:http://www.lthforum.com/bb/viewtopic.php?p=100194&sid=5c5722d1fb9bd6b1edd733d394e49941

Both Opart and House of Fortune are listed at Grubhub.com -that's another place to check for delivery options to downtown, they have a lot.
