Pen is usually right around 75-80% I believe - I never have taken a good look...I can try to ask around next time I'm out there
Min/Max on the main floor: the only 8 deck is usually $5, sometimes $10 on weekends; 6 deck games start out at $5 and will go up to $10 (again on the weekends/busy times); 4 decks are $10 or $15, although I have seen a couple at $25 min during very busy weekends; the double deck games are almost always $25 min. Max bet everywhere except the high stakes area is always $199.
There is another blackjack pit in a different part of the casino - all tables are 6 deck except one or two that are 8 deck - most run $5 or $10 min and again have that $199 max.
For those looking for a bargain, they offer $3 min on a couple tables Monday mornings
Anything else anybody wants to know? I'll get back to you on the pen when I can
