Top quality bar around. Atmosphere, lighting, decoration, music and of course the drinks. Negroni is top notch quality. Classic original cocktail bar standard you can find in Bangkok . Take BTS to National stadium station and take a 6 minutes walk to the bar. It’s in the same premise as Jim Thompson museum.

I wanted to try the OSS bar while in Bangkok and the place didn't disappoint ! We arrived during happy hours and enjoyed our cocktails, the bartender is really great. The theme is about the french spy OSS (french movies) and we loved the atmosphere, the decor. It was easy to feel like in a movie. The staff is professional and attentive, we received a warm welcome and decided to eat at the restaurant because we really felt good at the place.

The waitress was incredibly kind, one of the warmest welcomes I've ever received in Bangkok. I ordered the Jim Pinto, it was delicious. I could have stayed here all day enjoying the view and the music
