Interior of The Grumpy Mug

Not your average
drive-thru.

We started The Grumpy Mug because we were tired of coffee that tasted like burnt rubber and pastries that sat under heat lamps since Tuesday.

Located right here in Riverton on Federal Blvd, we focus on the simple things done exceptionally well. We grind our beans fresh every morning. We fold our dough by hand. We treat every cup like it's for a friend.

Single Origin

Ethically sourced beans roasted locally in Wyoming.

Small Batch

Baked in limited quantities to ensure peak freshness.

Come say hello.

We're nestled right on Federal Blvd, ready to serve you the best cup in Riverton.
