Can anyone recommend an affordable, healthy and tasty place to grab a bite to eat somewhere near Rector Street / Greenwich Street? I have been going to a gym down there, I get out at around 9pm and I'm famished. By the time I get home, I'm too tired and I don't want to cook, and it's also quite late to be eating. Not looking for anything fancy. Ideally somewhere near the 1 train... Any suggestions would be very greatly appreciated. Thanks!
