Well, I've only been here about 10 times or so and I'm not in the habit of making reviews on Yelp simply bc I'm lazy.
The fact that they have an awesome version of lentil sammich is enough for me to give 5 stars. But I'm pretty easy going and the people there are rather friendly, or at least, easy going and not uptight. Ambiance is cozy and pretty relaxed. I met a lot of randos there, which is nice, cuz I generally like talking to strangers. I like the wooden floors and tables...except for the Ikea coffee table that's near the couch. Industrial fan blowing is quite handy... given the weather tends to be hot and sticky.
I like that it's quiet when they're opened 24 hours. I get a lot of work done.
