Barely makes it to a three star because it's a good value. Nothing exemplary here and it's very popular nonetheless. I tried to figure this disconnect as I stood my twenty minutes in line.
The good: very reasonably priced breakfasts; has a lunch menu we didn't try. Really good service. Counter-culture ambiance.
The bad: inescapable noisiness, crowded, and you need to plentifully patient. Food is ok; nothing stellar but very reasonably priced.
This is not Denny's. If it wasn't for the wait, I'd probably go back. They really are working as fast as they can; they're friendly, it's not plush in any way, but at the end you'll probably be happy. The coffee is so-so.
