Here's an idea for a small bar in a corner that you could close off with beautiful draperies. The second photo shows a pretty bar cart which could hold the necessary items, and the third photo is of a simpler butler's tray.

Thanks, but I cannot find the track lights from Philips or Syska anywhere on internet or their website.

Sanchaya, In an ideal world you should look for module lights. But for a new person it may be difficult to work with it. If this is a  DIY project you can get LED Strip light in appropriate colors and then place a diffuser translucent acrylic to let the light pass through. In case you need further help you can call us for advise. Thanks, Nitin Cornerstone Designs Bangalore.
