I am trying to figure out a good location for a Sunday night (10pm-ish) low-key wedding after party near (walking distance) to Grand Central Station. Probably 40 people max. Ideally I would like a place with a semi-private area - this would be very casual; guests would pay for their own drinks etc. I like the Campbell Apartment but I'm not sure if it would be too crowded? Fonda del Sol is nice but closed Sundays. Any thoughts appreciated!
