The plantation is often the best choice for this, either upstairs or downstairs. I believe the price is 1000 for 4 hours plus 10.50 per guest, that includes dinner, beer, wine etc... you would have to bring your own sound system or rent theirs (way too much in my opinion). We bought the Bose sound dock, and bringing a microphone (note, you have to buy a mixer for the bose sound dock) for me, it was just a better deal
