Used to like this place for the "old school Vegas" feel and yummy greasy diner grub. And I guess I still do, but I was really bummed when I ordered a $9.50 margarita and got what tasted like a leftover margarita. You know like when you make a margarita and have some leftover in the shaker and all the ice melts and then you drink it sometimes against your better judgement...oh sorry. Yeah, I know what a bad margarita tastes like and I know at almost $10 a pop that shit better taste good. So I was really pissed when the server wouldn't take the drink back. She said that's why they suggest the 50 cent upgrade when they take your order. I'm sorry, shouldn't a $9 margarita taste pretty good to begin with? I asked her if i decided to upgrade would the bartender just pour the shot on top of my already crappy margarita and she said YES!!! At this point,(when i thought I wouldn't be getting my money back) I said sure throw some more tequila(and possible spit from the bartender) on my shitty drink. The drink comes back and Quel Surprise! still shit! Fuming inside, i thought I'd try my luck with the manager. She explained that it is their policy not to return drinks and that's how it is at most places on the strip, but she was kind enough(and seeing that i had barely touched the drink) to take the drink off the bill. I don't want to write off the Peppermill because it is fun and kitschy. I just know that i won't order a margarita there.
