We moved here from Northern NJ where a NY style deli is worshiped right along with any big religion yet in our last few years there, all the great NY style delis by us were closing in rapid succession. Going into NYC just wasn't an option each time I wanted some half sours and a knish. It took moving to Scottsdale, AZ to find a solution - go figure.
The gigantic menu you'd expect, pretty good bagels, great breads, not to mention the grilled cheese/Jewish sliders/patty melt/kosher dog with kraut/knish/fresh chips/potato salad/macaroni salad - all are awesome. I did not care for the Reuben I tried, however, I am crazy picky about corned beef and I realize that a true NY deli serves the meat a little fatty so that's my hangup. Husband had an omelet today that could have fed 4 people - he loved it.
If you are going to Chompies with someone and it is their first time, force them to look at the menu online first or you will be filling up on half sours for some time as they decide.
Great service, efficient but not pushy.
