We are sitting at one of the lime-green tables outside Seis Salsas next to another lime-green table of people who are beginning to feel good. For their next round, they are ordering frozen and not, salted and without. When our drinks come - tall glasses of pastel pink and orange garnished with glistening slices of watermelon and canteloupe - we are smug. Our neighbors look over and exclaim in that too-loud happy hour way, "What do they have?" Agua fresca. Who can resist the urge to tease mere margarita drinkers with watermelon water?
