CU 인천국제공항4호점

Small and crowded but efficiently managed. It has some variety of food, snacks, drinks... and you can get your wowpass here too.

I went there to top up my WOWPASS. It's located in front of the convenience store at the very end of the airport. However, since that's the only machine in the airport, there was a long line. Also, I gave up because they said you can't top up with Yen, only Won. The convenience store has a standard selection. It might be fun just to look around, as they have plenty of Korean-style items too.

Good

It's very spacious
