That's fairly late for lunch in midtown (other midtown counter-serve locations like Dig Inn and Chipotle seem sparsely trafficked when I show up at 3 PM), plus it was the Friday before Christmas. I wouldn't call low traffic under those circumstances "concerning" -- I'd say wait and see what things are like on a more regular date.
There's heaps of unhealthy fast food joints, the difference is the marketing. A Chipotle burrito has over 1000 calories but is perceived as healthy. That's twice the calories in a Big Mac.
Organic is good, responsibly sourced is good, but neither one automatically equals healthiness all by themselves.
Sure people are. Not enough according to you perhaps.
Sugar (not slow carbohydrates), and salts are the two main concerns.
All in all, I liked it. I got a very generously sized falafel quinoa bowl for ~$7 with an iced tea for an additional $0.95. For midtown, that's actually an incredible value. The food itself was good, nothing to rave about though. Concerningly though, when I went in around 2:30pm on Friday, I was one of the two customers there. The rest of the store was deserted.
There's no cashiers, just a bunch of self serve iPad stands with an clerk walking around looking to see if I needed help. The app on the iPad used for ordering was fast and fluid. My food was ready 2 minutes after I ordered.
