There's something about a trip to Papabubble that turns us into kids in a candy store––namely because, well, we are. Aside from offering treats in just about every flavor imaginable, the two Barcelona locations (one in the Gothic Quarter and one in Sarrià) also offer live candy shows, where you can see the magic-making process in person. So definitely stop by and pick up some sweet (pardon the pun) souvenirs to take back home with you.
