Which type of snack is the most profitable depends on local market demand and consumer tastes. The following are some potential snack bar ideas: 1. Traditional Soviet-style snacks such as siomai, soup dumplings, and xiaolongbao 2. Japanese cuisine such as sushi, ramen 3. Western-style pastries such as foie gras pancakes, custard cakes, and egg tarts 4. Specialty snacks such as kebabs, pancakes, and grilled bran 5. Internet celebrity snacks such as duck neck and braised food 6. Japanese and Korean snacks such as matcha desserts and Taiwanese milk tea 7. Momo, braised pork rice, fried chicken, and grilled meat in the center of the food street What needs to be noted about fast food snacks such as fish is that when choosing the type of snack, the cost and price of dish production should also be considered to determine the selling price and profitability of each snack.
