Will be down in SA with extended family and going to a show at the Majestic, and need a Sun brunch recommendation- ideally one in walking distance. We will be staying at the Gunter.

The Guenther House won't work for a party this big because it would be such a long wait.

Liberty Bar is walking distance and has a pretty good brunch with tasty cocktails. They have traditional American breakfast foods. Not sure how big your party is but you may be able to call ahead and make a reservation.

If you're up for a short uber there is Jardin which has delicious Mediterranean food at the SA Botanical gardens, NOLA (New Orleans), and Cappy's (American, has the best bread for brunch and a great tenderloin breakfast).
