This is consistently my favorite local restaurant. Rhett's has long had good vegetarian options including a daily soup selection, great salads with homemade dressings, vegetable plate options made with local and seasonal vegetables and a weekly ravioli selection. Recently, Rhett's added a vegetarian quinoa pie as well as several taste sized vegetarian options. Staff is willing to accomodate special requests. Calling ahead for unique requests may be a good idea as it will give Rhett and staff some time to wow you. If you can't call ahead, I always have good luck asking for minor changes or combinations of items to accomodate my diet.
Cons: limited vegan w/o special request
