I previously wrote that I'm not a huge fan of Gonpachi and think there are better places to take visitors. I'd like to offer my first suggestion for an alternative to Gonpachi: Teyandei, just a three minute walk from Gonpachi. A cozy izakaya with a discrete entrance on a street with more residences than businesses, Teyandei offers an "authentic" izakaya experience and the food is loads better than Gonpachi (in my opinion). You can order a la carte or order a "party plan," which starts at 3000 yen per person and offers a seemingly neverending parade of courses. The photos here are of the 3000 yen pp party plan.
Whatever you do, even if you are full, do not miss the baguettes packed with maple syrup and rich vanilla ice cream for dessert. It tastes so familiar, yet so incredibly unique - and in any case, is absolutely delicious (and is included in the 3000 yen party plan!).
Appetizer course: tamago rolled around unagi, sesame tofu and bamboo shoots
Cabbage salad with tiny dried anchovies, green onion and nori
Simmered pork covered with grated mountain yam
Deep fried mayonnaise prawns
Battered and deep fried potato wedges with a dipping sauce similar to tartar sauce (but with a load of MSG mixed in)
Wonton soup with succulent Chinese-style pork and chive wontons
Baguette, gutted and filled with maple syrup and rich vanilla ice cream - magically delicious!
