The Hostile Grape is inside the M Resort, which is off the strip as far south as you can get without leaving town.  The place has a wine cellar vibe on approach as you walk down a couple sets of stairs.  As you walk in you feel right at ease.  Great low lighting to set the mood.  Cool mix of jazz and electronica at a volumes conducive to conversation.  I'm not a wine expert but figured I would check it out.  Hundreds of wines to choose from either by the bottle or the glass.  Grab a seat at the bar or get a prepaid card.  With the card you can go around to a couple dozen wine tasting stations and have at it.  I got a single glass of white somethingorother for $10.  There is also a wide selection of beer and cocktails.\n\nI can see this place as a rendezvous point to start or end the night.  When I was there post midnight on a Friday there were a few groups but no major crowd.  Bartender said it's crowded earlier in the evening.  The Hostile Grape closes at 2 on the weekends, earlier other days.  In a 24 hour town that's actually refreshing.  Only beef is that being somewhat subterranean, I got no cell phone service.
