Firehouse Subs is a fast food franchise with 350 restaurants in 19 states. As the name suggests, the main staple of their menu is hot submarine sandwiches. The restaurant uses a steamer instead of a microwave to heat the sandwiches, which Firehouse Subs claims helps to retain moisture and texture during heating. This South Buckhead restaurant is located on the bottom floor of The Shops of Buckhead shopping center.
