Just food for thought, and I don't know what sorts of prices your local market commands, but we found it was actually cheaper to have our wedding reception at an all inclusive sort of place where they do the hall, the tables, the linens, the appetizers, food, the cocktails, the dj, the cake, the centerpieces, the menus, the seating cards, than it was to try to go a la carte. we also used a one stop shop for the limosines, the invitations, the photographer, the flowers, and they would have even done the wedding dress, the bridesmaids dresses and the tuxes.
having said that, think outside of the box, how about a cupcake shop, a bank, a mechanic shop/ jaguar show room, a greenhouse/ florist, a theater, a piano factory, a school, hospital, hotel, a bar, a restaurant, a bowling alley, a firehouse, the lobby of a commercial building, a coffee house, a wine shop, a brewery, a train station, an old slaughterhouse, a public library.
I am sure, wherever it is held, it will be memorable.
