RE: NYC soup shop---what is the name?
If tooslimnc ate on the block from 32nd to 33rd on the east side of 5th Avenue, he is out of luck as most of that block was torn down and there is now a skyscraper in its place.
Let your fingers do the walking. Go to the local phone company's online directory, superpages.com. Click on "Advanced Search", then click on "Search by Distance". For keyword, enter Restaurants. For search distance, set for 1/2 miles (yields over 800 hits). For street, enter "2 west 33rd st". For location, enter "New York, NY". Then select "Find It". A local map of the area pops up, along with restaurant names. Some cash-only restaurants are unlisted so the IRS does not find them. Some are listed under their corporate name. But, the map should tell you on what the street the restaurant was on, and you may recognize the name. As NYNM said, restaurants open up and close up all the time in that area.
I redid the search with business name "soup" (pulls listings out of the White Pages). I got Soup at 34 West 33rd Street, and Soup and Smoothie at 315 5th Avenue.
