Kanizanmai Shinjuku-ten

we ordered the king crab set, a lot of the reviews said it is too salty, but the taste is just right for me. Crab meat are very fresh, we also have the stove to grill the crab leg as well. Different style of eating while it is also good. Crab croquette is also a must try!! overall it is a good experience of king crab. one thing to note is that we have the stove for grilling, but our big jackets are just hanging right next to us, so there is a little bit of smell afterwards.

Took the 14000yen king crab buffet, it was good initially but the more you eat, the saltier the taste lingers in your mouth. The freshness is up there but you still have to eat moderately to really have the wow feeling. The crab cream is ok but the sushi over there is not recommended so save the space just for the crab.

Tonight, we ordered the all-you-can-eat King Crab set — something you rarely find back in Canada, so we were really excited to try it. Unfortunately, the king crab was on the salty side, and both my wife and I experienced stomach issues shortly after the meal. So while the concept is appealing, I’d recommend paying extra attention to the hygiene and food quality here.

First time having snow crab - no need to add too much shoyu or salt as it’s already a bit salty. Had the all you can and also the grill - I think it’s worth adding it since the grill menu is also unlimited. Bonus points given to service - they were attentive to me and was able to speak basic English.

100 minutes buffet. The crab is so-so. Flesh is a bit watery. Side dishes are ok. The rice with crab/sea urchin is the star dish. Very flavourful & well-cooked.

We enjoyed the private booth-style atmosphere, though the food was okay. The crab is definitely the star of the show, and we enjoyed it simply for the sake of trying something new. There is also a variety of unlimited sodas and other drinks. However, we were not instructed on how the ordering system works, which takes place on your phone via a QR code. We ended up wasting time waiting around for a server to take our order, as this is what we expected.

A Hidden Crab Paradise in Tokyo! Tucked away on the 2nd and 3rd floors of a karaoke building near Shinjuku, Kanizammai is a true hidden gem for seafood lovers. Don’t be fooled by its low-key location—this restaurant offers one of the most satisfying and affordable all-you-can-eat crab experiences in Tokyo! The course includes unlimited soft drinks by default, and for just ¥1,000 more, you can add a free-flow alcohol option with beer, sake, shochu, and cocktails. Start your feast with a generous serving of succulent crab legs, already cracked and full of juicy meat—satisfaction guaranteed. One of the highlights is the robatayaki grill (¥300), which comes with a complimentary kani miso crab shell and seafood for grilling—an absolute bargain. The menu also includes sushi, side dishes, tempura, and desserts, all included in the all-you-can-eat price. Despite the high quality and value, the restaurant is still relatively unknown, possibly because of its recent opening and inconspicuous location. That means no long lines—just good food and great service. One small note: the seating space is a bit tight, so larger guests might find it slightly cramped. But with delicious crab and attentive service, it’s still well worth it! If you’re craving crab and want a fun, interactive, and affordable dining experience in Tokyo, Kanizammai Shinjuku is a must-visit!
