Most of the time, "CPG's" is a cozy, sedate Main Street bar & grill situated about midway between Canisius College and University Heights, serving well-prepared comfort food and cocktails to the over-25 crowd. What it's best known for, though, are the sizzling blues shows that happen every Friday and Saturday night, where local combos like Dive House Union, the Jony James Band, and the Heavenly Chillbillies strut their stuff at the center of the Buffalo blues universe. Other genres like soul, funk, jazz and reggae crop up from time to time too, and if there's no band onstage when you visit you can still get your fix with the Internet jukebox and its encyclopedic selection of blues numbers.
