As it turns out, I actually went to the real "Soup Nazi" when he had the curbside kitchen ("Soup Kitchen International"). It was located near 8th Ave. & 55th st. And, trust me, the lines wrapped all the way around 55th onto 8th avenue and beyond. I got there at 10:30a so I believe I recall joining the line on 55th before it turned onto 8th ave. Still, the line did move quickly, as expected.
Most of the people on-line were well behaved and got their soup and bag of goodies, pretty promptly. There were only a few hecklers that ruffled his feathers (and he let them know about it), but most of them were not waiting in line. He actually greeted you personally (i.e. "May I help you?").. You gave him your order, you paid him directly and then you moved to the right to wait your order. You better know in advance what you wanted (most people on-line did) or read the menu board quickly.
I ordered an "Extra Large" Crab Bisque. You could see the empty containers stapled onto the menu board. it was $18.00. As he took my cash, he repeated back to me, "Extra Large" and I nodded. I watched him, and he actually got a "large" container (not "extra large") when he served me. Otherwise, no other issues. I certainly wasn't going to complain about it. I got my package and enjoyed my soup.... what less of it I got. And, trust me, it was good. You got the Soup, a piece of Italian bread, a small bunch of grapes and a macaroon.
I didn't get another chance to go back to him, but I probably wouldn't anyway. Still pissed off about paying for an extra large and getting only a large.
