Dive-bar row lost a legend last year when Quixote's -- which had replaced the even more notorious 7 South -- closed its doors at 7 South Broadway. But two newcomers are quickly filling the void. The hi-dive, which is coming on strong as a local indie-rock venue with creative programming, is a classic hipster-trash joint with minimal decor, a pool table and a pinball machine. The 'dive's popular Monday-night rock-and-roll movie series is a cheap thrill, offering $1 PBRs and $2 wells. Residing next door, in what used to be the smoking area of Quixote's, is Sputnik, which offers multi-hued faux-space-age lighting, black-and-white photos of NASA control rooms, and half-moon vinyl booths inviting patrons to kick back and enjoy the killer jukebox, whose selections range from Coltrane to the Meat Puppets. Houston, we have no problem here.
