Sub shops are peculiar. There are so many chains, they must find a hook to stand out.
Frankly, too many sub shops in this area appear a little too spartan, and possibly unclean. Service usually makes me think that the employee has been on the job only a few days and already hates the owner.
This Firehouse seems to stand out as an exception. It is very clean, and service is efficient and exceptionally friendly. The food does not really rise above expectations, a creation designed to appeal to a low common denominator while keeping costs down. But that applies to all chain sub shops, and this Firehouse, at least, is better than the competition (but see my review of the new Publix across the street).
