For a late lunch, I just enjoyed an intensely delicious "cheese steak" variant at a new place called Irving Irving, on Irving Place on the northeast corner at East 17th Street.
A plain, but very fresh ciabatta is split and filled with thinly sliced rare steak, lots of caramelized onions, and a wedge of Velveeta (I guess--I haven't had Velveeta in a long time, but it seemed to be, cheddary whey with Russian dressing notes?). This is placed between the searing plates of a sandwich press until grill marks form on the bread. Thus, 25 or so years late, Nouvelle Cuisine is visited upon the Cheese Steak sandwich. I know it sounds a little obnoxious, but it's actually worth a detour!
