Embassy Diplomat Screens is the go-to place for watching films with style ! Choose either from super comfortable seats to the full bed with blanket and private fridge while watching the movie of your choice.
For most tickets, you have included a private lounge with free food and soft drinks. With the VIP tickets, you even have beer and wine included!
Price is a bit steep, but think of it as a restaurant + cinema + VIP experience ;)
Also the cinema is inside Central Embassy, which is a luxury mall in Bangkok. Check Paul for some pastries, or ippudo for some ramen.
