Olimpia Newlove: The Born is a wonderful place to stop for lunch or just a midday cruise. Its chock full of delicious eateries and places to shop or have a drink. I recommend checking it out if you're in BCN
OK Apartment Barcelona: A wonderful marketplace in Barcelona from which you can buy some great local produce as well as exotic goods like edible scorpions.
Oh-Barcelona.com: The Magic Fountains are back onto their summer timetable. That means shows on Thursdays and Sundays again, as well as the Fridays and Saturdays!
