CSG Hospitality builds and runs neighborhood-defining bars and kitchens in the heart of River North. Nearly four decades of late nights, big games, private events, and the kind of Chicago hospitality that keeps regulars coming back.
CSG Hospitality is a family-run, Chicago-based operator of bars, kitchens, and event spaces. Our flagship, The Boss Bar, has anchored the corner of Clark and Hubbard in River North since 1987 — a true neighborhood bar that grew up alongside the city around it.
Today we're expanding the family. Coming soon at 418 N Clark: The Red Light Window, a River North pizza concept built around a walk-up window, late-night hours, and a classic Chicago sign of its own.
420 N Clark St · Clark & Hubbard
Nearly 40 years on the same River North corner. A proper Chicago bar with cold drafts, a scratch kitchen, a 12-panel LED wall for every game that matters, and a Back Bar built for the private party you've been trying to throw all year.
418 N Clark St · Next door to The Boss Bar
Pizza is making its return to 418 N Clark. A walk-up window, a neon sign, and a River North late-night concept built for the block that never really sleeps. Carbon black, glowing red, amber-lettered — and unmistakably Clark Street.
Private events, media inquiries, brand partnerships, or just want to talk about the concepts — the CSG Hospitality team is a message away.
