Shinjuku City, Tokyo, Japan｜JINJIN 新宿2丁目店

Casual and inexpensive. You can have larger spaghettis by nominal cost.

Tasty Pasta dish and good price.

I used to go there before they moved. Although it's far from Shinjuku Station, I still go there to eat on the way back from Shinjuku Gyoen National Garden. The main seats are counter seats, but they are high, so you may need to be careful when sitting with children. There is one box seat. Looks like it can seat 4 people.
