Kosher Subway on Avenue J
I think they have veggie subs. they definitely have tuna. I didn't see any kids meals there or any toys. also, I don't know about the magazines. but I prefer Sunsationals, its about half the price and there is so much more on the menu. yes, its EXACTLY the same taste as the non kosher subway, but after that novelty rubs off, you will realize that you are paying $11 for a turkey sub that you could get for $5.75 at Subsationals.
I hope my reply was helpful in some way to you.
