If you don't know about the four-bite burgers at Pair, you don't know jack (which, for the record, is pepper jack cheese, green chilis, tomato and horseradish mayo). The corner bar and restaurant at Sixth and Main streets in downtown evokes the spirit of joints many consider de rigeur in much larger cities, and mini burgers are hardly the haute cuisine one would expect to find at such a place. But it works. For the petite of mouth, the sliders amount to about six bites and for the big-mouthed among us, more like two. Get more than a dozen varieties with beef, chicken or veggie patties, topped with everything from cheese and bacon to a fried egg and onion rings. The Plain Jane starts at $2.50 while most of the sliders top out at a paltry $3.50.
