Miller's East Coast Deli. My absolute favorite to get is "The Dee" --- TRUST ME ON THIS ONE, IT'S MAD CLOSE.

Moishe's Pippic on Hayes is where I used to get 'em, and they were tasty.

also, I haven't had a NYC pastrami sammich, so trust agendacide on this one.

I have been to Moishe's Pippic, and while they were SUPER-NICE, I don't really remember their pastrami sandwich as knocking my socks off.
