Just outside of Piedmont Park (Atlanta), there is a restaurant called Park Tavern (formerly the Mill). There is patio seating and indoor seating, but the self-service seating allows dogs (either tied to the hitch outside of the iron fence, or - if you have a nice hostess - they can hide under your picnic table with you). The self-service is where you place your order & pick it up from the bar inside while your companion can be tied up or sit with your human friend. Perfect after a day in the park and the off-leash dog park ("Central Bark").
Lucky's Burger & Brew owners, Ernie and Diane Geyer, have their Golden Retriever "Lucky" as Inspiration for their restaurants (Roswell and Brookhaven). Hang out on the patio for Atlanta's Best burgers! Pets always welcome.
Grindhouse Killer Burgers is Atlanta's best burgers in a casual & fun environment. Crazy vintage robot themed design and a spacious dog-friendly patio overlooking Piedmont Ave. Water bowls are also provided.
