小龙虾（学名：Procambarus clarkii，俗称crawfish），夜宵界的实力霸主。Chinese people love eating crawfish （小龙虾）, nothing compares with washing down the delicacy with a glass of ice cold beer on a hot summer night.
Why so popular？
Crawfish has a strong adaptability to the environment. It's easy to breed it, and there's sufficient supply of crawfish. Therefore, compared to other seafood like lobster（龙虾）, crawfish（小龙虾）is much cheaper. Although the price increased after it became popular, it's still affordable for most people who love it.
The popular night market culture also promotes crawfish. After a day of hard work in the big city, eating spicy crawfish with ice beer seems to be a good way to relieve the pressure. In addition, it's a good way to eat crawfish with friends since you cannot play mobile phone with oil fingers.
High profit also attracts restaurant owners, and they try every means to promote their crawfish, like crawfish festivals, or hiring beautiful girls help you get rid of hard shell of crawfish. These means increase the publicity of crawfish.
