If you're trying to pick a city to visit based on the food alone, Barcelona is no doubt on the top of that list! Catalonian cuisine combines the very best elements of Spanish and French cooking with that uniquely Catalan flare that is unmatched anywhere else in the world. Knowing which items you NEED to eat when you're there will help you weed out the authentic recipes from the tourist traps.
If there one thing I like to do more than anything else it's to explore locals marketplaces. Whether it's a rural farmer's market no bigger than a few tables of tomatoes or a giant European market hall, there is something so exciting about being surrounded by a myriad of colours, aromas and flavours local to that city.
