I think Coco Banana is one of the best clubs on the Gongti strip, and with no cover it's definitely worth a trip if you're planning on heading to Mix or Vics. The music is pretty standard I'd say--mostly top-40 stuff and techno--but what sets the place apart is the atmosphere. The dance floor is small enough that even early in the night it's full enough not to be weird, and there is also ample bar space. The drinks are good (pretty standard for clubs here), but again what sets this place apart is the service. I was promptly served at the bar (something that almost never happens) and the bartender was friendly to boot. I think it's definitely worth a trip, and I'd recommend this place over many of its competitors that charge a cover.
