This neighborhood shop is an excellent place to study your fish and seafood kanji-reading skills, as the handwritten menu here can be rather difficult to read, even for the waitstaff. There's no prix-fixe option, although you can order a sashimi platter for Y2000 per person to start you off.
Drinks include around half a dozen premium sake to choose from, including some seasonal choices. Table seating is available if you're with a group and don't want to sit at the counter. Customers are all local, and ths shop is open late and open on Sundays (although they close earlier on Sundays, as most Tokyo restaurants do). Budget around Y6000-7000 at dinnertime.
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.
