You do the Varsity, because it's unique and an institution, and downtown, which is kinda neat. On a good night, the chili dogs are decent. The onion rings, too. Both the hamburgers and french fries are tasteless.
Zestos blows The Varsity away, when it comes to burgers. And, it can be an "experience" too, late on weekends. Ah, Glock 17 for me, with Gold Dot +P's.
Now, if you REALLY want a grade-A burger, and an entertaining dining experience, you head to Little Five Points, and hit The Vortex. Simple as that... The place has won "Atlanta's Best Burger", from more publications, more times, than I can count.
