I've been to this convention center many times - both as an exhibitor and as an attendee. I have to say, as a hotel convention center they provide all the basics. There's small food court outside, there's a Starbucks in the walkway to/from the Mandalay itself.. and a couple restaurants in the walkway as well.
Convention center south has three floors of space.. perfect for exhibits and educational sessions, and meetings, etc. Other than that there isn't much else to say - its a Convention Center!
