Rehearsal Dinner Question

What is the average price per person for a rehearsal dinner? What did it include?
Do any places let you bring in your own beer and wine?

Sorry for all the questions....but my cheapo FFIL is being a pain in the a$$ about it!!!

Depends on the place.

I found the least inexpensive, without sacrificing good food, was about $22.50 or $23. per person.

Some are buffet style and some are served to the table.

We are paying $36pp plus tax and gratuity.
(It includes beer, wine and soda.)
