Poker in New Orleans -- is there really PLO?

[sizeup]

Played @ Harrahs New Orleans about 1 month ago on a weekend.
5-5 NL had 1-2 tables going, good games but the max rake is $5.
There was PL Omaha High but I didn't play and don't know what the stack sizes or play quality were.
They had various holdem and omaha high only limit games up to 15-30 or 20-40, including some half holdem half omaha.
