I go to Murray Avenue Kosher quite often to pick up fish, bread and on occasion the prepared deli foods which are usually high quality. The service especially at the checkout counter is not customer friendly but not intentionally rude. I really like the kosher wine section as well as the large selection of smoked fish and kosher cheeses. Be prepared to pay higher prices than at the general supermarkets ( kosher is generally more costly everywhere). While the service may not be over friendly (although I have never really had a problem) I have always found the other customers to be both polite and often friendly.
