Most Chinese restaurants I have been to in the King of Prussia/Norristown/Wayne area offer a limited variety of dishes in their lunch buffet.
I stopped off briefly at the shopping plaza in Trooper, PA (2739 West Main St., Norristown, PA) across from the Firestone Auto Repair facility. I noticed what looked like a new Chinese restaurant (it is billing itself as "New Opening" for new managment, I guess). I expected to see the usual limited fare. Surprise. At least four areas of food, including the usual Chinese dishes. What was interesting was that among the many dishes were FOUR kinds of soup, sushi, salmon fillets, seafood dishes, and many many desserts.
These dishes did not look like they were of gourmet quality, but at $5.75 for all you can eat, Monday through Saturday for a lunch buffet, this restaurant is offering something attractive for the budget minded who want a large variety of food to choose from, at a very reasonable cost. Dinner buffets are $7.99 during the week. Weekend prices are a few dollars more (except for the Saturday lunch buffet).
I did not see vegetarian dishes featuring tofu. Their main menu is very limited regarding vegetarian dishes.
I hope this restaurant attracts customers, because for the variety of food they put out, they will need many customers to support their quantity and this area does not offer any other such restaurants with this kind of spread of food to choose from at these prices. I hope to try the food in the near future. I look forward to reviews of any lovers of Chinese food who try this place. (I would not expect these dishes to be described as "gourmet quality" but rather as acceptable for a $5.75 all you can eat buffet.)
I believe there is a similar Chinese restaurant that offers a buffet with a large variety of food at various "food stations", located near Germantown Pike on the other side of Norristown, up by Rte 202.
China Buffet is primarily buffet, seven days a week, lunch and dinner (although you can order from the menu).
