Subway - it's great!

Question

It was so nice to see young men with keepas eating at the W35th street Subway on the weekend. There were about 10 yeshiva students (black keepas, some with payot behind their ears), munching on what looked like delicious tuna sandwiches. I was there for a coffee, and when I asked them about the kashrut, they said not to worry, Rabbi Abada of Lakewood and Har Nof, attests to the kashrut of the place. Well, that was good enough for me so I too had a tuna sandwich and took a couple of subs to go. Thanks!!
