Ok, as a graduate of GT I know I'm biased, but I love the Varsity for what it is. Decent food with a charm and character that is unique in Atlanta. Don't expect anything gourmet here but the chili dogs are decent, the fries and rings are appropriately greasy, the fried pies are a treat and the FOs (frozen orange - think of an orange frosty) are yummy. We used to come here and sit in the car and we enjoyed every minute of it. Now I stop by on my way to an event in the city and still enjoy the hustle and bustle on gameday, the "what'll ya haves" echoing throughout and the energy of this place. Its a definite must-visit for out of town guests.
The Varsity has been around for a long time and is an iconic restaurant in Atlanta. The orange drink and orange frosty are both great classics. I like the hot dogs and fries myself to eat. They also have an ice cream bar with tasty ice cream. The service is exceptionally fast; they have perfected the art of moving people quickly through the line so you never wait more than 2 minutes even when crowded. The various rooms have televisions playing: some news, some sports, etc which is a nice touch.
Blt is located in the W hotel and has great ambience. We popped in for brunch and were a bit disappointed overall. Its pretty pricy for brunch($9 for fries) and the dishes were just ok. The restaurant had one other table occupied and yey we waited more than 30 minutes for our entrée....which were Luke warm to cold. The waiter was also quite rude and even had the nerve to say that's just who he is. I prob won't return, definitely not worth the price.
