Open since 1895, Imahan is one of the oldest sukiyaki spots in the city. Try not to drool as your server prepares the perfectly marbled wagyu beef sizzling in the shallow iron pot. Once the beef is cooked, it's presented to you dipped in raw egg (all that umami flavor!). End the meal with fluffly eggs scrambled with the remaining sukiyaki sauce. Oishii-desu!
