They have the usual drink comps (even at penny slots), though it would be nice if the servers came more frequently. I find the staff to be helpful and engaged (by this I mean, they seem to care about your having a good time). Having said this, the Casino is well kept. If you're in AC, and want Elegant, try Ceasars or Borgata.
This is meant as a description, not a criticism. Harrah's focuses on Festive, rather than elegant.
I wrote a somewhat longer review or the Property in General, so will focus here on the Casino.
