40/80 Lowball at Commerce

[jkinetic]

Greetings,

I am predomintantly a limit and no limit holdem player but am very interested in learning all games the best I can.

The few times I am at Commerce from the morning to the afternoon during the week, usually during a monster session of playing some form of holdem, I see this 40/80 game of Lowball going on with a bunch of oldtimers. They always seem to be the same people everytime, seriously, same clothes, always take the same seats, etc.

Few questions:

Is this game single draw or triple draw?

How does the betting structure work?

Is A,2,3,4,5 the nut hand?

This game mildly interests me as there are few if any low limit lowball games in LA to cut my teeth into.
