Lakeside Chinese is the small white building with the red roof on Lakeside Avenue. Their food is the best Chinese that I've found in the area (and believe me, I've looked). Their lunch specials are reasonably priced and they have a good selection of dishes available. The only problem is that their seating is limited (and on the day I ate in, they had no air-conditioning, either). But their carryout is fine, especially since it's not too far from my work =D
I've never used their delivery service, but I'd recommend them to anyone looking for good Chinese food. Their spring rolls in particular are very tasty!
