I'll admit that this location is extremely efficient and fast with the prep and the service is decent. The downside is that they do not participate in the $5 footlong monthly promotions anymore. I didn't realize that this was even an option for Subway restaurants! Needless to say, I was beyond disappointed when I found this out after stopping at this location.
