This little building at the Southeast corner of Two Notch & Covenant Roads is apparently an outbuilding on the L'il Cricket lot, or at least there doesn't seem to be a separate tax record for it. This Administrative Law Court decision (for Li'l Cricket's beer & wine permit) suggests that it was initially a smoke shop, but google says that more recently, it has been Willie's and Biddy's Corner Grill.
I was going to go back some later when I had time to stop and get closeups of the signs in the window and get a longer shot showing where it is in relation to the convenience store, but somehow I never did. At any rate, it is a tiny space, and looking at the windows, seems to have been mainly a walk-up operation.
UPDATE 18 September 2013 -- Here are some pictures of it as Biddy's:
and here it is in operation again as Wright's Eatery:
