Roof 409 is a rooftop restaurant and lounge located atop the Mercuryville Shopping Mall located at the corner of Rama I Road and Soi Langsuan, immediately adjacent to the Chitlom BTS Station.
If you look at the photo of Mercuryville below, the BTS ramp at left is Exit 4 off of Chitlom BTS Station. The outdoor rooftop area with the Roof 409 sign is clearly visible up above.
Once you enter the mall, you must go up an escalator to reach the fourth floor, and then work your way back to the corner of the 4th Floor that is closest to the Chitlom BTS Station. The entrance into the restaurant from the mall looks like this:
The indoor section of the bar, which can seat about 60 persons, looks like this, when viewed from just inside the entrance:
The outdoor, open-air section of the bar, which can also seat about 60 persons, looks like this:

The bar has two draft Vedett beers on tap, as well a one La Chouffe selection on draft.
This bar also serves a selection of craft beers in bottles – including: Duvel, Kwak, Triple Karmeliet, Trappist Rochefort, and Delerium Tremens Belgian beers, two Brewdog selections, and American beers from Rogue, Deschutes, and Anderson Valley breweries.
This is actually a bar and restaurant, with a serious European chef, who offers a quite sophisticated menu.
Music is easy listening pop and rock music, played at subdued level. Evenings, they have a DJ, and sometimes live performances. This is an upscale venue, with an upper-crust clientele, consisting of both Thai and foreign professionals.
Smoking is permitted only in the outdoor section.
Parking is available at nearby Mercury Tower office complex, which adjoins the mall.
The bar has no toilets of it own. The mall toilets on the 4th floor are located within 30 meters of the bar entrance. Exit the bar and bear left, and pass in front of the escalators to the wall on the far side – the toilet passage is then visible in that area.
The bar is owned and operated by Pierre, a Frenchman, and his Thai wife.
