China Dynasty is a Columbus institution that has been serving Chinese food since 1990 (1987 even, for the Upper Arlington location, which I did not visit). You only need to watch local broadcast TV at or around midnight to see a China Dynasty commercial, after which you will inevitably get the China Dynasty theme song stuck in your head ("China Dynasty...the home of the Happy Buddha,"...damn it, I'm going to be singing that song for the next week now!).
China Dynasty prepares inexpensive food that is better than its price range would indicate. It's hardly the top tier of Asian food available in the Capital City. However, the food is good quality considering its price point. There are a number of vegetarian entrees on the menu.
I started with a vegetarian spring roll. It is a Chinese-style spring roll, deep fried and filled with Napa cabbage, bamboo and mushrooms. It is somewhat bland, but the flavor is kicked up a notch by Chinese hot mustard.
The spicy bean curd is essentially a version of the classic ma po tofu (vegetarian note: ma po tofu is often made with shredded pork. At China Dynasty, it is recommended that you ask for the spicy bean curd without pork). Piles of tofu are pan fried in a spicy brown sauce with green onions and red peppers. China Dynasty does a solid job with a Szechuan standard.
China Dynasty has a full bar. The decor in the large restaurant is tasteful. The aim of the staff is to get a quick turnover at most tables.
China Dynasty makes solid if unspectacular food. Since it has a decent amount of vegetarian options that can be prepared quickly for a low price, China Dynasty is a good quality, inexpensive option for lunch. While you could definitely do better than China Dynasty, you could also do far worse.
