Host an elevated ice cream sundae party at this family-owned creamery opened by two longtime Harlem residents. Each kid (up to 12 kids) gets a scoop of homemade dairy or nondairy ice cream (flavors change seasonally). Your crew will lord over the whole place, which comes decorated with a dozen helium balloons, and you’re encouraged to BYO entertainment and food. If one scoop a kid doesn’t seem like quite enough, opt for unlimited ice cream with sprinkles and a cone ($12/child) or an ice cream bar with never-ending chocolate sauce and whipped cream ($20/child). All ages.
