I'd like to check this place out when I go to LV in a few weeks. For anyone who's been there: 1. Is there a cover charge to get in? 2. Do I need reservations? 3. Is it typically pretty crowded? 4. How is the ambiance? Is it loud? 5. I'm a 30-something year old here for a business conference, and would like to take two co-workers (both Vegas virgins) here to show them some cool sights - is my assumption that this is a cool place to do that correct? Thanks in advance.
