Our Story

More than a café — it's your third place

In N Out Smog was born from a simple belief: the best moments happen when good coffee meets genuine connection. Tucked along Harbor Boulevard, we've created a space where the barista knows your name, the music is just right, and there's always room for one more.

Whether you're grabbing a quick espresso between meetings or settling in with a pour-over and a book, this is your corner of Fullerton — no rush, no pretense, just real coffee served with warmth.
