Normally I am all about small business, "mom & pop" restaurants any day, but it is good to have a Subway, especially in downtown Matthews. Something about being able to get in and out pretty quickly and know that you are getting a consistent product in the form of a sandwich and your choice of toppings....
This location is one of the many eating choices you have in the Matthews area near Town Hall/Library. The parking can be an issue depending on what time of day you are here especially with the diagonal parking spaces and traffic flow.
Decent size dining room and patio and the sandwich artists are nice and courteous (as per their training I'm sure). Since the Subway occupies the end of the building row, it makes for an interesting layout (unlike the usual, strip mall longways set up).
