You are talking about the mixed games. We've had them at our room in the Aladdin and I can tell you from experience:

6 figure minimum buy in. Game changes every 10 hands (or when the players all agree). There are plaques that have the game listed on them that are random draw.
They play as low as 100/200 when there were only 3 of them playing and as high as 4000/8000 when the game is 7 or 8 handed.

Games included:
PLO
O8
O high
NL He (rarely)
Limit HE
PL HE
California Lowball
Kansas City Lowball
(A-5, 2-7)
5 card draw
7 Stud
7 Stud H/L
Razz
and variantions of draw games with a joker.
