Russ & Daughters Brooklyn Navy Yard

This is the largest of all the Russ & Daughters locations, and it has a big glass wall where you can watch them smoke whitefish, bake fresh babka, and boil bagels. More importantly, there's a counter where you can order pastries, bagel sandwiches, and other specialties - plus some seating if you want to stick around. Prepare to wait in line if you show up around 10:30 on a weekend (they open at 8am every day).
