Nook Coffee Bar

Rancho Cucamonga's coffee scene has a second tier forming beneath Klatch — small independents taking plaza suites and corner spaces, run by people rather than regional managers. Nook Coffee Bar is one of the names that came up repeatedly in our July 2026 research on that wave.

Here's what we won't do: pad this page with hours we haven't confirmed and an address we haven't stood in front of. This guide publishes what it can stand behind, so Nook carries an unverified tag until we've done the legwork — no invented details, no recycled listings-site copy.

If you're hunting for it, search the name and trust what the map returns over anything else you read. And if you know the place — or run it — we'd genuinely like to hear from you so this page can graduate to a full write-up.
