Yup, thats exactly my point especially for a new york first timer. I mean the steak house recs in this thread are great too, but do you really want to spend a c-note each at lunch? (I exaggerate, but only a little, depending on where you are going) and while the NYC steakhouses are top shelf, you can find good Steakhouse in other parts of the country. You are not finding Deli like Katz's ANYWHERE. Not even really in NYC anymore either. Nobody should go through their life saying they haven't tried reall NY Deli at least once. Its a dying breed (there a few I like, but thats another thread). 20 bucks for a sandwich you will be hard pressed to finish (but finish you will because its so frickin good).
By the way, The best Sandwich in NY right now (well my opinion, but it is my current fav) is right across from Katz's at Russ and Daughters and is called the Super Heebster.
http://www.russanddaughters.com/menu-sandwich.php It is SO good. I wouldnt recommend to a steak and burger guy or someone who is not familiar with jewish fish styles. In one gluttonous recent trip I actually ate one of those AND a Katz's Pastrami within 2 hours of each other. It wasnt pretty. But it was fun.
Just at Katz's recently, and maybe its just me, but I will take this sucker over a burger every day of the week. (notice the vet move of mixing in Full sours with Half sours on my pickle plate
