text: OMG THE ABSOLUTE BEST! If you're ever in Vegas and on the strip, stop by Cosmo and GO TO HOLSTEINS. \n\nOur waitress was impeccable and the best. I wish I'd gotten her name because she deserves a raise!! Best customer service ever!\n\nPROS: \n-burgers were cooked to absolute perfection and to the way we wanted.\n-shakes were to die for. foodgasm to the max. \n-fries were crispy and perfect.\n\nOverall, it was one of the best hamburgers I'd ever tasted and the best experience all in one. No doubt whenever I'm in Vegas I will make a stop at Holsteins!
