I'll admit I'm confused by this post. Are you having a party after the reception? Or is this for the reception?
At our reception, which would include dinner & the 4 hours of dancing, we had unlimited beer, but if people wanted hard alcohol, they had to pay. If we had a party after that, starting at midnight, then I feel like it would be acceptable to have a cash bar as you've just paid for 4-6 hours of drinking and food for everyone. Not to mention, if this is after the reception, there's only a couple of hours left to drink; I don't think anyone would be concerned about breaking the bank to pay for a few drinks after having been drinking all night.
