RE: D'Angelo Sandwich Shop
D'Angelos is chain, alright (and maybe belongs in the FFF). IMO it is a step above Subway or Quiznos because it is a regional chain and bases its menu and preparation on the local sub shops. For me, D'Angelo's is a reasonable choice when I'm hungry in an area where I don't see a decent-looking Mom & Pop, but I don't make a point to go there.
That said, they have been cross-branding with Pizza Hut and the like, and putting in mini-locations in gas-marts (as Blimpie's has) and the quality suffers in these locations.
They are also trying a new concept to compete with the nationals, I think it's D'Angelo's Grilled Sandwiches. I haven't felt the need to try it, yet.
