Union Pool is the spot to go when you're in the mood to mingle and willing to put in several hours to lock down a sleepover friend. Union Pool is a huge space: there's a large backyard with a taco truck, a barn-like second dance floor/bar, and a vast main entryway. This compartmentalized design gives you the feeling that you're at a house party, and this fact works to your advantage. 

The crowd here is relaxed, casual, and friendly. You won't feel weird joining in a stranger's conversation, and strangers won't hesitate to interject themselves into yours. Bonus: when chemistry strikes, the large space makes it that much easier to find a corner to make out in.
