You got that a little backwards. 6th Street between 1st and 2nd Avenues and "Curry Hill" are 2 different things. "Curry Hill" refers to Lexington around 34th to 23rd. Lots of Pakistani mixed in with the Indian restaurants, along with some amazing spice shops. East 6th is a residential block lined with Indian restaurants (although there have been a lot of japanese placed moving onto that block).
Minor quibble here- what you had was a "half-sour", and you’re right, it’s nowhere near as good as a "full-sour". I personally think you made a huge mistake in getting the corned beef over the pastrami at Katz’s.
Don’t tell anyone about Fried Dumpling!!! It’s always too crowded as it is. It’s my absolute favorite spot in the city for a quick bite.
Yeah, Famiglia used to be good, now they are a big chain, and not much better than Sbarro’s.
Thanks for the great report. Next time in NYC, be sure to get some real pizza, both kinds: brick oven (Lombardi’s is the Mecca) and standard Neopolitan pizzaria (there’s literally hundreds of great ones, my favorites are New Pizza Town on the UWS and Luigi’s on the UES).
