We love this coffee craver’s outpost on burgeoning Henderson Avenue for a lot of reasons: its funky East Dallas vibe, live music on the weekends, first-rate panini and hummus. (At a coffeehouse? Believe it.) But it’s the namesake Pearl Latte that keeps our caffeine-soaked heart pumping. What’s in it? Nobody there will tell us. The only secrets owners Carlene Saelg and Rita Davis would reveal are that it took them a year to develop the recipe and that they use beans from local roaster Clay Eiland. That’s it. After several sips, we’ve noted hints of vanilla, maybe even a small current of dulce de leche lurking somewhere beneath the latte’s satiny surface. No matter. Its soothing flavor and sweet mystery keep us coming back for more.
