The Original Brooklyn Water Bagel Co.

The in-store water-purification system is a focus at each location. Housed in a glass-enclosed room, it claims to process water (for cooking and bottled for sale) that replicates the water that flows “through the Catskill Mountains … into the homes of Brooklyn residents.” A new prototype takes the message outside with a water tower atop the store. It also marks the debut of dinner, a line of healthier dishes and a “coffee wall” with self-serve taps.
