The Carom Room in Beloit, WI has 34 or 35 tables - 23 upstairs and 9 or 10 in the new downstairs addition. Most are 7 foot Diamonds, but there are also quite a few 9 foot Diamonds, two Verhoeven billiards tables and a GC snooker table. Possibly a couple 9 foot GCs as well, but my memory isn't clear on that. The tables are well maintained and the lighting is excellent.
It also features a full bar and grill with great food. The jukebox has classic rock, country, some modern stuff but no hip-hop or ultra hard metal rock. When the jukebox is not being played they stream pop/rock/country from the late 50s to present. Plenty of TVs throughout the building carrying network sports and streaming cue sports.
I'm not sure of the prime time hourly rate, but they do have a special of $6.00 for all you care to play from 11:00am to 3:00pm weekdays. They have a thriving league and tournament schedule as well. Not bad for a town of about 30,000 people.
