private party, 50 ppl, Friday night in January

[Sophia.]

hi--

I need recommendations for a birthday party venue. here's my ideal party:
- 50-60 people
- Friday night 9p-1a
- DJ/dancing
- open bar
- light snacks + dessert/cake

I'd like somewhere we can get dressed up and not look or feel like fools, not a generic midtown/murray hill pub. my budget is around $5k. any suggestions would be quite helpful.

thanks!
Sophia.
