Never seen a PLO game under 2/2 @ DTD, but I"m sure they"d put on a 1/1 if there"s demand.
.50/1 NLHE tables are £40 min, £100 max buy-in, with no live straddles. People complain about the lack of the straddle, but if they want to play that they can move to a 1/2 table imo.
I"ll probably be there on the Friday night as well. I think a few others will be as well.
