Book & Stage started as Cosmopolitan's sports book, but now the area provides a comfortable and intimate spot (with great acoustics) to see free live music (the book has moved upstairs). What's more, the modest stage has attracted some of the biggest up-and-coming bands in Vegas, as well as big-name acts from all over the world. Shows generally occur nightly at 10 p.m. and midnight. Because the cushiest seats are first-come-first-served, get there early if you really
want to sit.
