our DQ here in Somerset Pennsylvania ONLY sells ice cream and they are open seven days a week..
they are slowly pricing their way out of the average budget, at least in this area, where there are NO jobs, just welfare and Social Security, youth leave here after high school..very depressed area...JMO
Granted, their sundays and blizzards are ridiculously expensive but their regular ice cream treats are less than $2 (cones, star kiss, ice cream sandwich). I’ve never seen a DQ that didn’t have a full menu of burgers, tacos, chicken, etc.
