Hi, I found a nice curry restaurant around Shibuya, so I'll write about that.
The restaurant name is "Jinnan Curry"
It's located in Shibuya, near "Bunkamura".
(2-23-11 Dogenzaka Shibuya Tokyo)
This restaurant is specialized in curry, so most of the menu is curry rice.
You can order naan instead of rice too.
When you visit there in lunch time, they'll serve you salad or smoothie.
It's not going to take time to get there, so please try this curry rice in your university life:)
