I had a weird experience here. Munchbar is located next to the Pure nightclub at Caesar' Palace and is a 24 hour bar/restaurant. Dropped in with the lady at around 1AM for a quick bite to eat. We ordered the steak and cheese sliders and the mini grilled cheese. the mini grilled cheese came with a thickened tomato soup-like dipping sauce, it was pretty good.
I asked the bartender for a frozen drink and she said that they didn't sell them but we could by them across the hall and drink them at the bar. I do so, and upon my return the manager/host ends up yelling at me asking me why do I think I would be able to bring that in. I explain that the bartender said I could and that my food was on the way, and I wasn't going to dump the drink I just paid for. He eventually moves our table and allows us to eat our food with the drink I purchased. The whole situation seemed totally unneeded.
