Jean Kerr said, "Even though a number of people have tried, no one has yet found a way to drink for a living." Ms. Kerr, I humbly beg to disagree.
The sangria at Pamplona's Tapas Bar is legendary. There is red and there is white, and while both are delicious I would recommend to try a taste of both to see which you prefer, and when it doubt order the one that most reflects your usual wine tastes. The white is infused with pineapple for sure and other fruit flavors without being sickly sweet. It's refreshing and its alcohol content is relatively low, which is good when you are plotting 12 hours walking around under the Louisiana sun.
This year, however, the sangrias are a bit harder to find. Usually sangrias are served outside. Now Pamplona's built a special room on a side of its building, just to the right of the balconied tables. Basically, it looks like a confessional for booze. It fits no more than a few people on the other side of the bar so there is this rather fun, illicit feeling you get, like you're about to drop code words to the door guy to get into the speakeasy. Go in there and let em know the code is "please serve me the largest sangria possible."
