Katie Holmes, Victoria Justice Chow Down on Mind-blowing Burgers and Shakes

This milkshake brings Katie Holmes to the yard, apparently.

Katie Holmes, along with actress Victoria Justice, were two of many glamorous guests who showed up to celebrate the grand opening of Black Tap Craft Burgers & Beer at The Venetian Las Vegas.

Justice was joined by her boyfriend, actor Reeve Carney. The All-American actress chowed down on Black Tap's All-American burger, naturally.

Holmes slurped up their signature Cotton Candy CrazyShake and we're told she and Suri are already big fans of Black Tap’s New York City locations.

If it's good enough for Suri Cruise, it's good enough for the rest of us!

The Vegas joint opens to the public today.
