This was our last meal in Vegas before hopping on a plane and getting back to reality.  Knowing that Burger Bar is a Hubert Keller restaurant, I went in expecting a lot...maybe expecting too much.\n\nYou basically build your own burger here.  There are so many choices.  You get to pick your meat, bun and your toppings.  I went with the Black  Angus Beef Burger with bacon, grilled onions, sprouts and bleu cheese( http://static1.px.yelp.com/bphoto/DUT55eQDtMPNZgyjN_JvKg/l ).  I swear the restaurant wasn't very busy, but the food took for-e-ver to come out, and we were huuuungry!  After watching food pass us by to other tables, our food finally came.\n\nFor a $14 burger(after all my toppings), I was expecting to have a super orgasmic experience when biting into my burger.  The burger was good, but definitely not the best burger I've ever had.  The meat was nice and juicy, but  the flavor didn't wow me.  \n\nAgain, service was sloooooow.  We were done with our meal, and we wanted to pay our bill so we could head to the airport.  Our waitress was nowhere to be found.  We finally get our bill and want to pay it, but again, the waitress disappeared.  Maybe I was just more irritable because I was tired and hungover.  But it seriously seemed like we waited forever.\n\nWill I come back again?  Maybe.......they do have a Kobe beef burger...hmmm.
