Asagaya is one stop away from hip Koenji on the Chuo line, and a few stops before Kichijoji on the same line. It is surrounded by cool neighborhoods, but is still an understated fun place to visit. It's developping quickly and has a lot of nice fun and small bars and restos. You need to stop by if you love international cuisine in an unpretentious setting.
Want to eat amazingly good middle-eastern foods until you're about to burst? Zakuro is where you should go! On top of the great food, the place is so authentically decorated that you'll feel you've been teleported to Turkey!
