I think my favorite food stop at the MN fair in relatively recent times is the New Prague Hotel (don’t know if it’s still there — the actual hotel in New Prague, MN closed several years ago, but its food-only fair offshoot stayed on). They had a Czech sausage called Jternitze (sp?) that was terrific. Not on a stick, just on a bun, with kraut and/or mustard.
Worst newer-fangled thing: Deep-fried Twinkies. The batter throws the divinely ordained starch-to-creme ratio way off.
The hotel and restaurant in New Prague was one of our favorite haunts when we lived in Prior Lake. Six or seven course meals, then upstairs for an overnight stay in one of their rather small hotel rooms.
Pity, it’s been closed for several years...
