For some, there is nothing better than a good, old fashioned Jewish Deli. Schlesinger's fits the bill nicely. You really can go wrong with any of the sandwiches (especially their breakfast sandwiches). Consistently good food at good prices.
This kosher butcher has a ton of variety. All kinds of meat, chicken and a bunch of different Israeli products. All kosher meats are also Halal. For the Muslim neighbors of the northeast, this wonderful couple would love to make their top quality meats part of your next Eid celebration. There's the standard selection of kosher meat products, but also a lot of specialty things -- house made sausages and different kinds of burgers.
Great little neighborhood deli / meat store.
