Good butcher shop just south of 90 on Warren Road/W. 150th Street. Friendly staff and a varied selection of meat (especially sausages), seafood, deli and prepared foods - with a few other niceties like bakery items and to-order sandwiches.
As many have noted, they have fantastic smokies, regular and spicy. They do some in-house sausages including the best chicken sausage I have ever had. Reminds me of some great old stores I shopped at when growing up in NY. Living far from K&K is tough since I moved from Lakewood, but I still make the trip to get my fix.
