I have lived in Las Vegas for five years now and have eaten regularly at almost all the Roberto taco shops around town, and never have I once ever given them a complaint until now especially having to do with this location on Harmon. At first it kind of pissed me off that I had to go back out to my car to get my wallet and pay cash, cause if you want use your credit card at this location no matter what the total is they want to charge you a flat rate of $1. That is totally absurd to me. Also their salsa bar was a complete mess... there were cucumbers in the hot sauce, carrots in the green sauce, jalapenos and onions in different places than what they should have been, and there was only 2 customers in the restaurant. They were not that busy so I'm sure the guy behind the counter who stood there playing on his phone probably could have cleaned up the hot sauce bar. Also, while I was waiting for my food I noticed a sign by the hot sauce bar that said please only take what you need so we can keep our prices low. I thought that was pretty funny seeing how they're ripping off every single customer who uses their credit card by a $1
