I have had an intense craving for a meatloaf sandwich for about two weeks now. I really know of no good options in Manhattan. I work in Tribeca/Chinatown, so reccos down there would be ideal, but I'll hop a subway if necessary if the quality is right. Years ago I used to eat one from Boston Market when I lived in Boston, and it was, believe it or not, quite good.
Believe it or not... They're still pretty good! Different locations have greater or lesser success. The one in/near Coney Island in Brooklyn has the best Boston Mkt food I've ever had, and please resist the urge to say "That;'s not saying much" I'm not saying there isn't better meatloaf to be found, I'm just confirming that they still do a good job and, unlike most restaurants, they have it every day. IAdditionally, f you call around to local diners, they will tell you which days they have meatloaf as a 'special'
