390 Social is a stylish neighborhood bar and private event venue in Park Slope known for its lush, nature-inspired design, warm lighting, and easygoing Brooklyn charm. Guests step into a greenery-forward space with cozy banquettes, wood accents, and a cocktail-focused bar program that favors fresh ingredients and approachable signatures. While it functions as a convivial bar for everyday gatherings, 390 Social is especially geared toward private events—from birthday parties and engagement celebrations to showers, corporate mixers, and boutique weddings. The venue offers flexible room configurations suited to both seated dinners and standing receptions, with thoughtful touches like dimmable lighting, plantscaped backdrops for photos, and music-friendly sound options. Private bookings can incorporate cocktail-style menus, dessert tables, or family-style catering via outside vendors, and staff can assist with timeline planning, décor layouts, and AV coordination. Reviewers highlight the welcoming team, streamlined planning, and the room’s photogenic greenery that gives events a relaxed, elevated feel without heavy décor needs. Cocktail standouts lean toward classics with a twist—think bright spritzes, spicy or citrus-forward tequila builds, and seasonal gin and vodka infusions—alongside a concise beer and wine selection. Full or partial buyouts are available, with capacities that fit intimate gatherings as well as lively receptions. Whether you’re curating a micro-wedding with a ceremony backdrop among plants or hosting a casual mixer with a DJ and passed bites, 390 Social balances aesthetics and functionality for a polished, low-stress event in the heart of Park Slope.
