Restaurants are bumping up to 50% capacity on Monday so that should be helpful although you should still check the hours and days before you just show up for a meal. The capacity limits in the casino were always a joke because they were including conference space in the square footage calculation which essentially meant they didn't have to turn anyone away in the casino although sportsbook seating was and will be problematic.
Still seeing very random acts of violence that they try to keep on the QT. After midnight, I would consider outside walking somewhat risky. The fronts of Ballys, Planet Hollywood and the Bellagio seem to be magnets for troublemakers, thugs and hoods.
