Ibiza calls itself a "fisherman's diner," and this unpretentious neighborhood spot offers a great selection of fresh-caught fish and seafood. Simple home-style recipes rely on the high quality of the ingredients rather than showing off any dazzling cooking tricks.
On a recent visit we enjoyed kisu (whiting) fritters flavored with ume and shiso; big portions of miso-simmered ginmutsu (bluefish); and first-rate grilled salmon belly. The hone-sembei (toasted mackerel bones) were crunchy and very tasty, and the cold chunks of cucumber in miso-meat sauce provided nice contrasts of flavor, texture and temperature.
If you're a fan of craft sake you'll probably find something to your liking on the extensive list; they also stock various Chinese liqueurs and ten kinds of umeshu. Budget around Y4000 with drinks. Note that the menus and service are in Japanese only, and the restaurant is quite busy, so bring a Japanese-speaking friend if you're not comfortable negotiating the menu.
This book will introduce you to more than twenty of Japan's favorite specialty foods that are less well known abroad, along with a guide to the best places in Tokyo to try them and expert tips on what to order. From Bento.com.
