There's plenty of people who eat and drink (mostly drink, usually from cans) outside once every week or two in nearly zero (freedom degrees) temperatures. Often they also light a pile of pallets (and maybe even a fiberglass boat if the wind is right) on fire for warmth.

It just so happens that people inclined to do these things have mostly all been driven out of major urban areas where the restaurants are and if they weren't they would mostly still not go downtown for overpriced beer.
