The signature dishes are paper-wrapped fish and double-layer charcoal grilled bullfrog. I ordered them and they tasted pretty good. The lady boss is pretty and enthusiastic, and the dishes are served quickly. The taste is also good, and everyone is quite satisfied!
There is a buy two get one free promotion at Thirteen Spices, so the price-performance ratio is pretty good. It is quite flavorful, and I personally prefer spicy.
