Visiting barcelona in 2 weeks, need some tips

I would like some tips on where the locals would eat,supermarket.
I don't want to follow the normal tourist path.
Thanks:)

You probably just need to go on either barcelona-underground.com, or even tripadvisor.com to find out the best places to eat out in the city. if you're thinking food shopping though you are going to get a much better deal at the markets than in the supermarkets. Even La Boqueria, which is on the busy street Las Ramblas, is cheaper than supermarkets like Carrerfour etc. Maybe even half the price for vegetables etc..

Just the vegetables. In general, supermarkets are the best option + a market for vegetables! Anyway, if you're not in the "center" of the city the prices are fine (except for 24/7 markets, obviously):D
