I have no opinion on the merits of this particular place, but I feel like between Shake Shack, B.Good, Five Guys, Smashburger, etc., the general space is due for a market correction, somewhat like the Cupcake and Froyo Reckonings that have taken place in the past year or so.
The Chipotle format mildly annoys me because it lets you customize everything as if the restaurant has no viewpoint on what are the better combinations of ingredients.
