This seems like a restaurant that cannot find its identity. Currently there are signs hanging up outside with three different names. (I think they actually dropped the 18Burgers, possibly with some encouragement from 25Burgers down the road. In any case, their menu lists only 14 burgers.)
On another note in the same strip mall (at Routes 79 and 516), it looks like "Chelsea's Creamery" has finally opened as Chelsea's Ice Cream, after years of a sign saying it was coming soon.
