We stopped in here for lunch while visiting Harajuku on holiday. Great place for a quick lunch bite.
I had the Karaage set meal which was tasty and ample for lunch.
The place is fairly easy to find and a short walk from Harajuku JR station: From the station exit cross the street at the pedestrian crossing (toward the building with the GAP sign), head toward the pedestrian overbridge, (Don't use this), but at the intersection turn left down the main road. After a couple of hundred metres you'll come to a major cross road (Meji Dori), cross this and continue. At the second small street on the left, turn left. Vegecate is about 100 metres down on the right with a distinctive green sign.
