At LAB, the passions of chef Sergi Arola are found on the plate. The Spanish-born chef grew up cooking, but he harbored dreams of being a rock musician, too. This juxtaposition plays beautifully in bold, artfully crafted dishes and a striking, 22-seat space where a glass-block wine cellar takes center stage. The restaurant holds a Michelin star, drawing visitors from Sintra, throughout Portugal and beyond.
