Your family owns that joint, or did you just work there? I have never, ever, passed by without the appropriate indulgence. It is a big part of why Malta is on my wife's list as a possible retirement locations, with DQ helping balance the scales of immense skeeter numbers and harsh winters when measured against the virtually untouched walleye fishing nearby.
I used to stop there every time I was in town, but now I have to stop at Ray J's instead. Not unusual to still get a Blizzard from time to time.
Retire to Malta? Interesting.
