I did the trip 2 months ago on the overnight train.

You get 2 seats facing each other then they convert to a top and bottom bunks, they will make the bunks up for you when you want.

When you wake up they convert them back to seats for you.

There are about 20 bunks in each carriage.

Bottles of beer are served at your seat also water juice etc and the server will take your order for food, they serve a meal about an hour after you leave bangkok its pretty basic but tastes good

If I remember its about 5 or 6 items from soup rice curry or noodles coffee etc

They will also take an order then for your breakfast.

Just before you reach Chaing Mai they give you a bill for what you have had during the trip.
