nice bar/good wine/big group/takes reservations?
Preferrably downtown. nice atmosphere. doesn't have to be trendy.
I went to a birthday gathering at Employees Only and I know the hosts made reservation. Cocktails are expertly made, very classy place. It's a little too-too, sure, but everything is really well done. Plus they have food (big and small plates) if anyone wants to eat. We were seated in the atrium out back.
