I found a couple with 10/20 limit.
Also if enough request, they get up to the 10/20 and higher NL.
2/5 NL will be my max if I even decide to play any.
I welcome you to call them or show up and ask if they'll spread a 10/20 limit in between the 8/16 and 15/30 games which run daily.
I played in that room weekly for the better part of a year.
Unless they've radically changed the 8/10 and 15/30 games, I'm pretty hard pressed to think they'll open a 10/20 table.
