I think it was Frank Van den Bosch's Chicago Billiard Café. Seems it's still in business:
Established in 1984 by the Van den Bosch family and sold to the current owners in 2008, the Chicago Billiard Café has been a local and family-owned business for over 20 years. In its heyday, the Cafe was home to many of the city's best players and a standard stop for some of pool's modern-day legends. Regulars included Freddy "The Beard" Bentivegna, Billy Incardona, Efren Reyes, Raymond Ceulemans, Roberto Rojas, Jeff Carter and Leonard "Bugs" Rucker -- all legends in the game. Today, as one of the city's last remaining true pool halls, the Cafe continues to cater to pool aficianados as well as amateurs of all skill levels. We have top-of-the-line equipment with 16 nine-foot regulation size tables, most of which are Brunswick Gold Crowns covered in top-of-the line Simonis 860 cloth. Additionally, we have one of the city's few snooker tables, a 12 ft. antique covered in directional cloth imported from Ireland.
