Krave was the first gay club I ever visited, so I guess that's why I hold it close to my heart. That's also why I'm probably willing to overlook some of it flaws.
Positives: Centrally located and essentially on the strip. Decent sized dance floor. Bartenders are friendly. There's a really good mix of people from all walks of life. I've always enjoyed the selection of music (ranges from your typical pop hits to house/progressive/trance). Lastly, HOT HOT HOT dancers!
Negatives: $20 cover charge for non-locals. Boo! Drinks are a little on the weak side. Seems like every time I go, any sitting location is for reserved parties only.
Other than those negatives, I've never had a bad experience at Krave. Those used to clubbing in San Francisco or Los Angeles might be a little disappointed. That said, Krave will always be near and dear to me, even though I've seen far better clubs.
