As of the end of 2017, Okadaya has 12 stores, and its branches can be found in almost any business district in Shanghai, which is quite influential. Okadaya, which is a crab, will open stores in Beijing, Suzhou, Hangzhou, and other places in the future.

Okadaya, a crab house, supplies fresh king crab, hairy crab, snow crab, and golden king crab every day, with clearly marked prices, freshly killed, and diners can also order crabs directly in front of the fish tank. The restaurant has a wide variety of crab recipes, including sashimi, boiled food, grilled food, salads, and sushi. If you want to talk about the signature dish, it has to be the snow crab pot. First of all, the paper pot is eye-catching enough as a cooking utensil; Secondly, the bottom of the pot is only a broth cooked with kelp and bonito flakes, which is simple but can bring out the umami of the crab to the greatest extent; The soup base with crab and vegetables is used to make soup and rice, and it tastes great. In addition, the combination of seasonings is not sloppy, the crab vinegar has a refreshing taste without a pungent industrial taste, and the grapefruit vinegar with radish puree is also very appetizing.

The service in the restaurant is Japanese style and to the point. When you enter the restaurant, the waiter beats the drum to welcome you, explains the ingredients and how to eat the food after serving, cuts the crab legs with the help of the snow crab pot, and says loudly in Japanese, "The customer is going back" when you leave, and then all the waiters at the restaurant thank you in unison. The restaurant has a lively atmosphere and the atmosphere is perfect for gatherings. There are private rooms in the store, but they are not suitable for business.
