Has anybody in the UK ever spotted one of those coffee-house thingies over here?

I have only the haziest idea what Americans mean when they talk about them. Sounds like a restaurant that serves neither hot food nor alcohol and has both floor spots and resident musicians, which here would stay solvent for about a week. Is Tchai Ovna in Glasgow along the lines they mean? (They only keep going by using premises on the edge of going the way of the House of Usher and furnishing the place from skips).

Anyway, we never had them here to abandon and we certainly aren't taking them up now.
