The Rehearsal Dinner for my wedding party (which was a long time ago BTW), was at the New Orleans Manor in Nashville. It was an expensive seafood buffet and it was excellent. At the time they actually had Maine lobster tails on the buffet, as well as, a number of other seafood delights. The restaurant itself was in an old mansion built sometime in the 1800s. So it had a very nice atmosphere as well as some very good seafood (even though it was a buffet.)
Now that you have me thinking about that, the next time I visit family in Nashville, I may have to make a trip to to the Manor and see if it is still as good as it used to be.
