Tequila trip!

As part of the launch of his new spirit brand, Casamigos Tequila, George Clooney stepped out on Tuesday night to celebrate its launch at Rocco’s Tacos in Ft. Lauderdale, Fla.

The Descendants actor was there with his fellow founders Rande Gerber and Mike Meldman to sample cocktails and mingle with locals.

“George and Rande did not separate the entire night. They both drank the Casamigos specialty cocktails being served,” an onlooker tells PEOPLE.

The “really friendly” Clooney also took time to take pictures with “almost every attendee at the event,” the source says.

“There was one woman taking photos with her iPad and George was helping her get the best shots – he kept calling her ‘the iPad lady’!” the source adds.

The promotional tequila tour – which is expected to bring the actor to L.A., Las Vegas and Dallas – kicked off with a short film starring Clooney, Gerber, Cindy Crawford and Stacy Keibler. In the minute long film, the group of friends play musical beds after a night out of drinking Casamigos.

On Wednesday the tour continued in Las Vegas with Clooney, Gerber and Crawford stopping into Andrea’s inside Encore Hotel to indulge in some Asian cuisine. After greeting fans, the group enjoyed sushi, ribeye steak and vegetable sides. Following the meal, it was off to Surrender Nightclub where they continued to enjoy tequila and vodka for several hours.
