Jerry Jeff Walker immortalized it in song. Chain restaurants often lace their margaritas with it. Even Boone's Farm has a version of the concoction. In spite of all that, we love that sangria wine. And at Spanish tapas bar Cafe Madrid, we really love it. Their sangria is a mixture of red wine and...well, we can't tell you the rest, something about a "trade secret." But whatever, the stuff is good, and in the summer months, you can opt for a white sangria that's made with cava, a Spanish sparkling wine, and some other stuff we can't tell you about. It's cool and refreshing and yummy, and the mystery just makes it all the more exciting. And if you like to do a little snacking with your drinking, the eatery's tapas selection offers some excellent complements to the fruity beverage. Just a note, though: If, like us, you've never been accused of being the brightest crayon in the box, and you can't figure out why the menu doesn't make sense, look to your right; the other side is in English. Yeah. Have some more sangria.
