Not sure if it is LB friendly but I agree it looks nice. I definitely want to go to one of the rooftop restaurants when I am in Bangkok.
There are a few more also : Sirocco,vertigo,breeze etc.
Most are listed on trip advisor if you select the "view" filter in "dining options" - http://www.tripadvisor.com.au/RestaurantSearch?geo=293916&pid=&q=Bangkok%2C+Thailand&cat=&src=
