Zeke's has regular 8-ball on Friday night, 9-ball on Sunday night.
Oasis has 8-ball on Friday and Saturday night, 9-ball on Sunday night.
Wolftrap in Edmond, a close suburb, has Saturday night 8-ball. 12 Valley tables.
Sunset has a tournament, can't remember which night.
All are bars / clubs.
As previously mentioned, check with Jamaica Joe's. It's a pool hall and they have regular weekly tournaments, plus special tournaments often. I think it's 8 ball on friday on bar tables and then big table 9-ball on Wednesday. May be another one also. best equipment in town.
Also, look here and try some of the others listed. We quit publishing the paper in February because we couldn't deliver with the high gas prices, but the locations and phone numbers are there and accurate.
