The Terminal is a local favorite; it is located in a 3-story building with a ton of character, features a large menu with an extensive selection of beer, and even has a brewery inside. I think it has one of the best burgers in town as well, one that is frequently overlooked when I hear others discuss who has the best burger.
Specifically I am talking about the Philosopher's Burger. Order it medium, and it will arrive grilled to mouth-watering perfection. The burger is ground lamb seasoned with cinnamon, oregano, shallots, and sea salt. It is served with feta aioli and candied red onions. And it is Good Lord good.
I make trips specifically for this burger. Starting the meal off with the FESTO bread is a great way to wait while your burger is prepared, and that brings up my final comment about the Terminal. If you put your name on the waitlist, they take your phone number and send you a confirmation text. You can then see your current wait time, modify or cancel your wait, or let them know you are on your way to check in if you are notified while away from the hostess stand. It's the first I've seen this system in Chattanooga, and it works well considering the Terminal's popularity and small waiting area.
