(so $10 pass line on a $10 table and they'll let you do $5 behind). You can actually put less than a unit behind for odds and they'll still pay it out. One nice thing (well nice for those who feel like doing it!) is you can do 'baby odds'. The nice thing is they DO grandfather you in so if you're lucky enough to catch a low minimum, you can stay that way for a long time (played with a guy a few months ago who had been there for 12+ hours at $5!) Occasionally they'll have a $5 table on during really slow days/hours but that's been more and more infrequent. Table minimums are generally one table of $10 and one table of $15.
The two in the middle are generally only open on weekend nights after 8 pm.
Two are by the sportsbook/sports bar area which is on the left side of the casino and two are in the middle behind the 360 bar. My wife and I go to Ilani to play craps just about every single weekend!
