At Casa Mono, the Foie Gras ($19) is of a perfect portion for lunch. Dinner here is chaotic and so is brunch, but a late afternoon lunch is the best time for a relaxed meal. Here it's piled high above two crostini, laced in balsamic vinegar. The foie gras itself is barely seared, a slip of a crunch on the outside and pure fatty bliss all the way through. Cut off a piece of the crostini, a fat wedge of foie gras, and spoon on a tiny bit of of that thick, savory-sweet sauce. "Cinco cebollas," the five onions—including green onions, cipollinis, leeks, white onions, and pickled red onions—is key. They make for clean and crunchy bites with a bit of sweetness, giving the dish a necessary balance. If you're craving carbs to pair with the foie gras, consider the reliable Patatas Bravas ($9), a generous bowl of crisp fingerling potato halves paired with a paprika-sweet tomato-based sauce and thinly cut leeks.
