Those pockets look huge.
Standard pocket size on the tables was/is 5", the Diamonds that came out with their 4.5" pocket size on the pro tables makes the rest look large. I have not checked all the pockets, but I would say they are 4.75" - 5". Play fast also. The cut of the pockets to be more flared than Diamonds and the shallower shelf makes them play easier.
They have a tighter GC II (pretty sure it's a 2) and a 3C table there also, along with some nicely setup Valley 7" tables.
I have gone there a few times but mostly for charity tournaments. That's the place I won my Lomax cue at.
