Sekai no Yamachan
Sekai no Yamachan is a relatively cheap Izakaya-style restaurant. It's quite a popular place to go to have a few drinks with colleagues or friends, but it also has some kid friendly menu items so basically it appeal to everyone.
Nagoya-Style Chicken Wings
The thing that comes to everyone's mind when you mention Sekai no Yamachan are its famous and so addictive spicy tebasaki!
They are deep fried and glazed with a soy-sauce and mirin based spicy sauce. At Yamachan you can get 5 chicken wings for 430 yen. This is considered a one person portion but they're so tasty that its easy to eat much more than that! People in large groups litterally order a mountain of chicken wings!
A tasty way to have them is to sprinkle the wings with sesame seeds.
Nothing goes better with Nagoya tebasaki than a mug of cold beer (480 yen)! Pitchers are 1,480 yen. Kaku highball, a mix of whisky and soda is another popular drink here. You can choose between a single (6% alcohol) for 390 yen or a double (13% alcohol) for 520 yen.
Chicken wings are obviously the most popular items here but Yamachan also has a very wide choice of other dishes such as nabe dishes (hot-pots), Japanese curry, salads and many other. There is also the pretty popular nagoya miso kushi age (deep-fied pork skeweres in red miso sauce) that you should try if you go there. Nagoya is very famous for its red miso.
Order to take-out is a popular option too. You can even buy the chicken wings frozen directly from the restaurants and bake them at home.
