Bukkake Udon is a local Kurashiki specialty. Contrary to what some foreigners think, there's nothing strange or funny about it for the Japanese. The name comes from the verb "bukkakeru" meaning 'to splash/pour', because you pour on the sauce yourself.
The original version is served cold however, you can get it served hot as well. They also have many varieties and toppings available (the dishes served with meat are only served hot).
I am a fan of udon, so I always enjoy trying new kinds. I had the normal kind (except I got it served hot), because I think it's good to try it that way the first time, but a lot of the other varieties really looked good, like the kimchee bukkake, the beef, pork, etc. It's very affordable and although there are a few locations, one is conveniently located in the shopping arcade near the station.
Koimari is a cafe located in Kurashiki's Bikan Historic District. It's in one of the historic buildings. It has a charming old-world European feel inside. As a cafe, they serve many drinks, like coffee, cafe ole, cocoa, and many teas. For food, they have hotcakes, toast, cheesecake, and zenzai. It's a nice place to relax as you're exploring the area.
