I was Yesterday in a original indian food restaurant in barcelona, the adress is c/ Bailén 61. For me was it the best original experience I found in Barcelona, and maybee in some other countries. The website ist no very nice http://www.indianrestaurantbarcelona.es/ but the restaurant more nicer you see in the pictures, and the people very helpful, theyh explain you all disches, this is important to know, because if you don't know the indian food it's very helpfull. They also have possibilities to take away and they tell me they also bring the food to your hotel. A good tip if you are in barcelona and want to try something different than tapas and paella.
