Martinez (great option for lunch the food is great and you also get amazing views of the city) 

Bar Canete (one of the best tapas spot in Barcelona also the restaurant is wildly popular and you need to call at least a few days in advance) 

Bar Brutal (they have the staple tapas menu like cheese and olives the majority of the main dishes will vary with the seasons and change day to day depending on what's available at the market) 

EL Chingre 1769 (one more tapas bar but this one focuses on offering serving classic Catalonian & Asturian dishes 

Bar Mut (this tapas spot is memorable for anyone that went because the food is delicious. They have specials on the whiteboard everyday, but make sure you get there early because they don't take reservations) 

Mont Bar (this is a more formal and fine dining style tapas restaurant that has unique and creative dishes) 

Bar del Pla (want a quick bite to eat? Or you are alone and want somewhere you can eat alone yet not feel alone? This is the place for you)  

Disfratur (this is the kind of restaurant that you want to gatekeep. But it’s too good and fun not to share. It is a modern Michelin restaurant that offers set menu that is so experimentative and unique that it will be a meal you won’t forget)
