I love this place, #13 is one of the best Italian subs in the Charlotte area*. I grew up in Matthews so I have been eating here for about a quarter of a century back to when it was the K-Mart/Kroger parking lot. The owner and his daughters are incredibly quick on the slicers and can tear through the long lunch lines that they have for obvious reasons. I personally don't smell the smoke anymore but remember when it was a smoking restaurant so that may be a viable complaint. I also remember them having beer but I think that was a long time ago.
*The others were "Deli Queen" in Spanish Trace near McAlpine and "Sub One" in 4th Ward.
