Not sure if this is a reasonable price for my wedding reception or not?

This is a great price! This breaks down to about $40/person. I don't know how prices are out in Tennessee but Maryland is very expensive, and I wouldn't be able to host a reception for that price. And not to mention, it's a complete plus that you can bring your own liquor and cake, because buying your own alcohol will save you a ton of money! And the cake will save you money, because you can either have a friend do it, or just purchase a small 1-2 tier fancy cake from a bakery and a sheet cake that can be cut up in the back and served. For that price, its definitely worth paying for over self-catering and stressing about how things will get done. Sit back and relax and enjoy your day!
