CNN Travel features Alfresco 64 - A Chivas Bar at the Tower Club lebua Bangkok.

24 Hours - 'In Bangkok the worlds highest outdoor whisky bar.' CNN's Karla Cripps reports.

Though you're not going to be able to rock up and order a beer -- staff made it clear this joint serves only whisky -- there's no need to worry if you can't stomach a Yamazaki single malt on the rocks.

Alfresco 64 has a nice menu of excellent, creative whisky-based cocktails, including our favorite -- the Cloud on 64 (check it out in the above video).

Other sophisticated touches include specially selected glasses and carafes designed to enhance the whisky-drinking experience.

"We always want to do things where we change people's perceptions," Deepak Ohri, CEO of Lebua hotels, tells CNN Travel.

"Whisky was a serious pastime and we wanted to bring fun into the experience and create a lifestyle and we are lucky to have brought this aspiration to life with our partnership with Chivas brothers." So far, says Ohri, the response has been amazing.

"Revenue wise we are doing three times what we budgeted for," he says.

"We serve nothing but whisky cocktails and whisky -- oh and water and ice! The most surprising aspect is that at Alfresco 64 we have more Thai clients than foreigners and this is what we wanted -- to change the way whisky drinking has been."
