This may be old news for some, but the Botanical Garden Cafe is open (again), but the menu looks to have really changed (used to be Lee Epting and more sandwich/soup sort of menu):
... the newly renovated Gardenside Café at the State Botanical Garden is now open under the management of Countryside Catering. Lunch is served from 11:00am – 2:00pm Tuesday through Sunday (closed on Mondays).
[Menu includes] pulled pork, baked beans, cole slaw, Brunswick stew, bread or a variety of sandwiches and salads.
For detailed information on menu selections, daily specials and pricing, please call the café at 706-542-6359.
Members of the Friends of the Garden receive a nice discount.
