The price of fish maw varies significantly, depending on the type of fish. Cai says that a kilogram of dried fish maw on the market can be bought for as low as 800 yuan ($115.5). High quality ones, on the other hand, can cost a whopping 30,000 yuan per kilogram.

"What we are using for the hotpot are South America fish maw from croakers. They are good enough and affordable to most diners," says Cai.

At Biao Ge, a half portion of the fish maw and chicken pot sells for 218 yuan. This includes 125 grams of fish maw, 125 grams of fish fins, and half a chicken. The rich broth is full of umami while the fish maw has an addictive, bouncy texture.

Apart from the sumptuous broth, other standout dishes at Biao Ge include the chicken feet stewed in soy sauce and fried tofu that comes with a crisp outer layer.
