If you’re looking for authentic Mexican food with a lively atmosphere to match, make a run to East Williamsburg’s Mesa Coyoacan on your next date night. The neighborhood is unassuming, so the romantic interior here will come as a bonus surprise, with exposed bulbs and candles casting you both in flattering light. Conversation flows as you note clever touches like the arrays of vintage frames, and the flowers used to obscure a back staircase. An outgoing staff has you feeling welcome, and intimate seating boosts the energy. Traipse through the margarita menu and see who’s got the courage for a chile or habanero infusion. When it’s time for dinner, you’ll enjoy sharing with each other, as you sample small plates that let you mix and match. Feel like you’ve traveled across the border as you dig into sophisticated takes on classics like cactus salad, tacos, quesadillas, and tamales. Order the mole enchiladas and you’ll be in on a secret: The chef’s closely guarded family recipe is used here, upscaled with organic chicken and crema fresca. For dessert, indulge in another family recipe, as you and your loved one mingle forks on a tres leches cake made with tequila, mango, and strawberries.
