Being from NYC originally, I know good Jewish delicatessen food, and Kornblatt's is the best I have ever had west of the Hudson River! Even the free pickles that come with every entree are super-crunchy and actually snap when you break them, a rarity anywhere outside of New York or a Bubby's jar. They even carry Dr. Brown's sodas, an authentic NY deli staple.
My only complaint is that the staff is far friendlier than any deli in NY. But that's a good thing. I haven't had a single thing here that has disappointed yet, from the authentic potato knishes, homemade latkes, and kugel, to the matzo ball soup and smoked whitefish salad. I eat here whenever I'm in the neighborhood, which is chock full of great restaurants. One of the best in Portland, no doubt about it.
"The secret of great matzoh brei (aside from lots of butter) is a proper balance between crumbled-up matzoh crackers and the eggs that bind them. You don't want it too eggy, nor should the matzoh be dry. Kornblatt's version is a very good one."
"Kornblatt's is a neighborhood storefront that locals love for the food as well as for service that can range from motherly-nice to deli-counter crabby."
