Wagamama

Wagamama is a Japanese pasta and rice restaurant. There are different kinds of pasta: thick pasta in soups, thin fried pasta, wok pasta with vegetables, sauces of varying degrees of spice. The concept of Wagamama is that you eat at big wooden tables, sharing the space with other people. It's kind of a noisy place, but it's got a great, lively atmosphere.
It's ideal for big groups because everyone will fit at these tables. The appetizers are little plates of fried foods with typical Japanese sauces. Going out is pretty expensive in Copenhagen, but Wagamama offers a complete dinner at a pretty low price.
