One area where Barcelona does not lack, is it's incredible array of restaurants, strewn throughout the city. It has a vast range of high-end, greasy spoon, moderately priced and authentic places to grab a bite. The influx of expats and tourists over the years has greatly influenced the cuisine, providing the city with a Mediterranean fusion feel often combining Asian dishes with Spanish tapas, Italian plates with Moroccan amongst a host of other combinations.
When it comes to great eateries near Barcelona's Camp Nou Stadium you're in luck as there are some tasty options either very close by or just a quick walk or taxi ride away. Although Camp Nou isn't in the heart of the city center where many of the well-known restaurants take up shop, it's a well-known established area thus attracting a wide range of quality restaurants. The stadium itself has a few stands where you can get food, but if you're in the mood for a more elegant or elaborate meal either high-end of more economical, definitely check out the surrounding area either before or after the game. Or even if you're just touring the stadium, grab a bite with your guide or with your group in the area, it'll make the experience that much more authentic if you eat in the same vicinity as the stadium.
