There are so many burger places in Vegas and my favorite is still Bachi Burger.\n\nSo burger bar is a not too trendy burger joint located in Mandalay Bay. They have build your own burger concepts but we decided to be safe and ordered the hang over and the lamb burger. I've had great lamb burgers in the past and this has got to be one of the most disappointing lamb burgers I've ever had for $20. As for the hang over, it's decent but it made me crave for in-n-out because it is the exact same burger except it is $13 versus $5. Everything was just underwhelming and lacking in bold rich flavors. At least the portion sizes were decent.\n\nThey do have a build your own milkshake, but since I'm lactose intolerant, I'll pass on liquid death. :(. There are so many other options which makes it hard for me to recommend the Burger Bar.\n\nOverall, meh for me.
