It doesn't surprise me that Lit has a 4.5 star rating on Yelp. I can't say much more than what others have already said... But i'll say it anyway.
Besides the fact that Stumptown Roasters is incredible, Lit is always (cheesy alert) service with a smile. Their prices are so reasonable, i absolutely love the vibe in there at all times (especially Saturday mornings) and they've always got room for me. And to be honest, you have a special relationship with the other regulars that if they're sitting alone at a table for 2 they'll offer you the other seat.
With the new addition of their Cold Brew, Lit is THE place for coffee this summer, and all subsequent summers.
I love this place.
