Bar cars were more common during the time of World war in US.. I don't think so now it's having such a great demand.
Best Old Bar Brought Back to Life Denver 2011 - Bar Car
By last summer, the Recovery Room was a neighborhood joint in need of a nip and tuck — which is exactly what it got after Leigh Jones, the proprietress of Horseshoe Lounge, Jonesy's EatBar and the new Stingray, took control of the space. Today the boxy little bar is one of the city's most glorious watering holes. Antique brass chandeliers illuminate the rustically romantic space, which is filled with cherry-red stools, Victorian-era upholstered banquettes, an ornate tin ceiling, a pinball machine and one of Denver's best jukeboxes. And that's just setting the stage: Add convivial tenders, good bar grub and a swell beer, wine and spirits list, plus a nekkid pic of Burt Reynolds in his younger years, and you've got everything you could want from a bar...plus a whole lot more.
