About

Relentless Grind is tucked inside Roadside 22, which is worth knowing before you go looking for a separate coffee shop. There's a long counter, tables and booth seating inside, plus a patio out front.

I stopped in on a Sunday morning and got a cold brew with a splash of vanilla and cream, plus a jalapeño bagel with cheese. Both were fantastic and a great way to start my Sunday.

From Matt

Good for

  • Sunday morning coffee, meeting someone for coffee, or hanging around instead of just grabbing it to-go.

On record
