Since its a private restaurant, I would think very early. We made them about 4 months out I think. You wont regret the Gospel Brunch- best buffet on the property!
It was outstanding, IMHO, and I love buffet breakfasts. We started with mimosas and went from there. Lots of savory meats, eggs, fish. There's breads, waffles, and cornbread etc. Salads, Shrimp and an omelette station.
The music and tone of the music is Gospel, make no mistake. We're Christian, so we enjoyed, but anyone would like the energy!
The food was great, I ate way too much. I wish I were going this Sunday!
I hope things haven't changed and that you really love it too. We were asked for a credit card to hold our ressie (or did we pay in full?) Why not just call them?
