Your Office Party, Somewhere That Doesn't Feel Like the Office

From an Intimate Department Dinner to a 400-Person Celebration

Company holiday parties tend to happen in one of two settings: a generic hotel ballroom, or a rented-out restaurant that still looks like a restaurant. 501 Union is neither. A Brooklyn landmark venue with a 50-foot skylight, exposed brick, and handcrafted chandeliers, the space can flex from an intimate department dinner to a 400-person company-wide celebration.

Chandeliers, string lighting, brick, and a marble bar mean less decor spend to make the space feel festive — many companies use the Cocktail Lounge as-is for a lower-lift holiday happy hour. With several tiered bar packages and the ability to build a custom cocktail menu, holiday party planning doesn't require sourcing a separate bar vendor.
