They're definitely open
I just came back from there and had a great time. I picked up some very valuable info too. Be warned, it's definitely a counter trap as they have taken some unusual measures to catch counters. I can't elaborate on here for obvious reasons. Also if you play there, don't expect to eat there unless you wish to wait in line forever as the casino only has one restaurant open usually and that's the seaside cafe. For logic that totally escapes me, the buffet is closed on most days including Friday nights.
