Good question -- It's hardly a deli-- really more of a storefront for take-out. At the North Avenue location, there is no seating.
In response to the other post above re: the amount of fat: I, too, would be disappointed if the corned beef were really lean. That's no fun! The sandwich we had today definitely had a lot of fat throughout --without the fat being "gross" or excessive. I actually liked the bread-- not a true rye -- but more of a thinner, softer, seedless rye.
I also noticed that the North Avenue location was missing from the corporate web site.
I'd love to hear if others have had any experiences here -- or with other items on the menu, including their cakes, pastrami, other meats, etc.
