Lanna Thai @ Face Bangkok Still Open?

We have a brief stopover in Bangkok enroute to Copenhagen with a 5-hour layover on 25 August 2018. I was hoping to use this time to have a traditional Thai dinner in one of the elegant teakhouses and Lanna Thai @ Face Bangkok came to mind. I have eaten there some years back and really enjoyed it.

A friend once mentioned that the place could have closed down for good. Can anyone verify if this is correct before I finalise my dinner plans.

If, it is in fact no longer operating, any suggestions for a nice Thai dinner in a fanciful old Thai mansion would be appreciated. Grateful for links to their websites too.

Thank you in advance for your kind advice and recommendations,
