Everybody's favorite late-night den, bar, and disco is the Bar Rotliechtli, which somewhat provocatively translates as "Red Light Bar." It's also known as Cava Grischi, near Postplatz, just off the main street of Davos-Platz (tel. 081/414-90-00). Warm, cozy, cramped, and convivial, it offers a rustic-looking decor of varnished pine and masonry, free entrance, and a bar that caters to all ages and all types of personalities, provided that they're late-nighters looking for interaction with like-minded extroverts. It's open nightly from 8pm till around 2am. Beers cost from 8F ($6.55/£3.40) each.
