I've culled 30 threads to try to come up with places that are at least 90% guaranteed to have hot donuts, paczki, or fried dough when you ask (either cooked right then to order, or coming from constantly hot batches), and am not having much luck.
Save me from Krispy Kreme - where can you sit down or walk in, order a fried dough product, and have it placed in front of you piping hot? The only places I've experienced this firsthand are Hot Chocolate, Tru (!), and street fairs. I've been to Abundance several times and have never seen anything remotely warm. Does Harry Caray's serve fried dough as a dessert at the restaurant (they have it at the Taste sometimes?) Anyplace with fresh paczki year round, where you can get at it hot at certain times of day? Hot beignets would fit the bill too (Nola's Cup in Oak Park does well in this regard).
