Grande meatball.
Pappardelle.
Tomahawk.
The above is the minimum you should order if you are with 2 or more people. Or if you have an appetite like mine...
Andiamo is casual, yet you should really put on some pants and a nice collared shirt for this place. You'll get the same great service if you come in wearing flip flops, T-shirt and shorts as you would wearing a suit, so no excuses to not dine here!
Been to Andiamo at least 6 or 7 times now and it is my favorite restaurant in downtown Las Vegas.
