Barcelona: Reliable Chow/Drinks Near Camp Nou?

[Howgart]

Hi All...Will be attending a football match in Barcelona in early February. Can anyone recommend a reliable spot near the stadium (preferably walking distance) to chow down and have a few drinks before the match? Not looking for anything real formal or fancy. A place to grab some decent tapas and a few beers/glasses of Cava would be perfect. Thanks.
