Where does the locals go to eat crab in Sapporo?

Sapporo kani-honke is faimous restaurant in sapporo.You can eat several crabs &crab couse there.

I have met few people from Hokkaido, but for people in Hokkaido, crabs are not a thing to eat outside usually. They buy raw crab (sometimes a live crab!) at fish market or supermarket, and boil it at home.
