Everytime I go to this Firehouse subs I am so well pleased and satisfied with the service and friendliness of the emploees. They always have smiles on their faces and say "Welcome to Firehouse" no matter how slammed or dead they are in store. I'm not sure of everyone's names but I went today around 12:30pm-1:00pm for lunch and the whole team was just absolutely amazing and so fast. I do know the name of Dalton and he is so kind and you can tell he takes pride...

After an appointment nearby, we went to Firehouse Subs for a late lunch. I had the a small drink and a Firehouse Hero Sub which included roast beef, turkey, ham, lettuce, tomato and mayo placed in a sub roll. I would have rated the experience as excellent if the sub roll was fresh. Unfortunately, it was not. Also, the service was at best mediocre. As a result of this experience, It may be a while before we return to this Firehouse Sub restaurant.
