Park Slope has a tranquil, easygoing vibe and can almost feel suburban. Strollers and children of all ages are a constant presence on sidewalks, as are shoppers patronizing local boutiques and dog walkers heading up to the park. Residents are Brooklynites through and through and tend to be socially conscious, artistically minded, and committed to their community. At night, a casual restaurant scene comes alive. For anyone looking for a night out, there are plenty of beer gardens and wine bars to patronize, especially in the South Slope, but don't go looking for dance clubs.
