Miami's good evenings are neighbourhood evenings, and each one has a different temperature.
Little Havana. Calle Ocho after dark is the most alive Miami gets without a cover charge. Live son, salsa and timba play most nights at venues along the strip, several with dance floors where the standard is high and the welcome is genuine if you are willing to be bad at it for an hour. Eat first: a sit-down Cuban dinner, then a mojito, then music. On the last Friday of the month Viernes Culturales closes part of the street for a free arts festival, and that is the single best night in the neighbourhood.
Wynwood. Breweries, small bars and galleries in converted warehouses, walkable, casual, loud on a weekend. Second Saturday gallery nights are an easy, free way to spend an evening.
Brickell. Rooftops and river views, the dressiest of the mainland options, with the Metromover free until late so you can leave the car behind entirely.
Coconut Grove. The quietest and the most under-recommended. Waterfront tables at Dinner Key, tree-shaded streets, and a village centre you can walk after dinner.
Miami Beach, done properly. Skip Ocean Drive and use Española Way, Lincoln Road's side streets, and the Sunset Harbour and North Beach neighbourhoods, which is where people who live on the island actually eat.
A note on cost. Miami is an expensive dinner city and the service charge is frequently added automatically at 18 to 20 percent, particularly in South Beach and on the causeway islands. Check the bill before adding a second tip on top, which is the most common way visitors overpay here.
