This is essential information whether you want to admit it or not. It's as important as knowing where the ATM's are with the lowest fees and which casino has the best cashback and video poker paytables.
So, which casino has the best public restrooms?
I'm going to list four of them, but I'm not sure if one of them still exists:
1. Pechanga (OK, it's not in Vegas) in the high limit room. This is open to the public even though it's in the high limit area. You do not have to place a bet. The men's room always had an attendant in there keeping it clean, private stalls with sinks in the stalls, exceptionally clean sinks, beautiful fixtures.
2. M Casino, not on the casino level but just below it (use the escalator or stairs) to the restrooms by the meeting rooms, banquet rooms, convention rooms. Modern and beautiful.
3. Caesars Palace, outside the entrance to the Forum casino and down the escalator/stairs. Clean and well attended.
4. Mandalay, in the high limit room. Now, it's been several years since I was there but what I remember was an upgrade of what you'd find at Pechanga. And as a bonus, there were free "freshen up kits" including toothbrush and toothpaste, disposable razor, cloth handtowels. Does this still exist?
