My girl friends and I kicked off our Vegas weekend with a late and light lunch at Holsteins.  I was salivating when I saw Billionaire burger ($28) on the menu with kobe beef, foie gras, port onion marmalade, frisee, and truffle mayo, but I decided that the Hen House burger ($14) was good enough for half the price with its fried egg and bacon.  That is, until our server highly recommended the award winning Gold Standard burger ($17.50) with dry aged beef, bacon, goat cheddar cheese, tomato confit, baby arugula, and garlic chive aioli.  It was done--I would eat the winner.\n\nAlthough complex and tasty, the Gold Standard didn't make me shake my buns or roll my eyes backwards.  I didn't care for the fancy stuff like goat cheddar cheese, tomato confit, or baby arugula.  For a gourmet burger, Umami Burger (multiple locations in LA and one in SF) is my gold standard and it's about 2/3 of the prices here.  I did, however, enjoy the shoestring fries at Holsteins.  They're skinny, crisp, wonderful, and plentiful.  \n\nIf you have a car in Vegas, you should make the trek to Bachi Burger (http://www.yelp.com/biz/bachi-burger-las-vegas).  Now there's a burger joint worthy of being called the best burger in Sin City.
