The charming couple behind Mandolin Aegean Bistro and Mrs. Mandolin lifestyle boutique and café expanded to the Vagabond Hotel with Gregory’s Diner. The all-day American eatery serves elevated, standard diner fare such as flapjacks and club sandwiches. Being foodies, they added fancier dishes like whole roasted fish and beef tartare along with a full cocktail menu. 7301 Biscayne Boulevard; 305.846.9130; gregorysmiami
