Try Pitkins in Schroon Lake, which is about halfway between Albany and Montreal. It’s a short drive off the Northway from either Schroon Lake exit, on Route 9 in the center of town. Good home style meals and great pies. They also advertize barbeque but I’ve never tried it so I can’t comment on the quality or authenticity.
There are a couple other places on the same street which I’ve never tried.
