Lately, one of my favourite food is the Yatai Mura Nabe 屋台村鍋, which is available at the Nippon Yataimura Japanese Restaurant. This is like a spicy seafood steamboat. My wife and I each ordered one for dinner the other day.
The Yatai Mura Nabe has all sorts of seafood including prawns, squid, scallops and fish. If you wish, you can ask for rice or noodles to go with it, but I prefer to have it as it is, as it is sufficiently filling.
