A branch of the very popular Nagoya izakaya chain, Yamachan is a great place to sample local Nagoya delicacies in Tokyo. Recommendations include the awesome spicy chicken wings (we prefer the regular wings to the sauce-coated "black wings"); super-crunchy deep-fried prawns; and richly flavored dote-ni (miso-stewed pork entrails).
If you want something filling to finish off your meal, the spicy "Taiwan ramen" is a faithful rendition of another classic Nagoya dish. Drink options include a couple of local craft sake, miso-flavored beer, and the usual cocktails, shochu and draft beer. Budget around Y2000-2500 for dinner.
Note that this is one of the rare branches of Yamachan with a dedicated non-smoking section, and as such may be popular with families with children early on weekend evenings.
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.
