That would be the Chef Sau, no din sum. The food is greasy and over priced. There is not a single asian restaurant worth a damn west of Worcester until you hit Amherst. The Eastern Pearl in Webster is ok if you're looking for American Chinese food but if you're looking for the real deal you have to travel. Worcester has a pretty wide spectrum of eateries but I think there's room for small niche places that serve up things no one else offers like din sum. If you make it, they will come and if it's really good the line will be out the door. If you are the entrepreneurial type, Worcester is a college town and students come from all over, talk to them, ask them what they like, what's good back home.
