I've always wondered what happened to Arby's, the roast beef sandwich chain. It seems like 15 years ago or so there were a bunch of them here in MA, but gradually they began disappearing for some reason. Today there's only three left in the entire state. I had assumed the chain was going under, but last weekend I was in Buffalo and, lo and behold, Arby's is alive and well in the Buffalo/Western NY area. There's even a stand-alone franchise in downtown Buffalo where there's otherwise not much in the way of fast-food options (yes, you bet I ate there and pocketed some Arby's sauce packets on my way out the door).
Anyone understand chain location criteria that could shed some light on this situation? What explains why chains abandon certain locations, concentrate/expand in existing ones, and ignore other markets?
