Well, yes it's common knowledge that certain wines "favour' certain wine glass shapes.
Liquor laws are kinda funny here and you need (or used to) have a certain kind of license for byob. Don't know about now.
I don't have a problem with byob provided, as Pete says, you call in advance, and I would charge a corkage fee too. I would politely refuse to wash your glasses, as they are expensive and much more delicate than regular commercial stemware.
Heck, if you're gonna bring a 160 bucks worth of stemware, then you're probably gonna bring at least a 150 buck bottle, and that means you're gonna blow at least 100 on food, so I don't mind, not at all.
But that's wine.
But the guy who brings his own plate and cutlery, and his own meat to a restaurant... That's asking for trouble. Dude's already made up his mind that your place sucks and he'll be whining and moaning like shot bearings in a power steering pump all evening. Dude's got to ask himself why he's even out of his home in the first place.
Snausages? Did you want to interject here?
