freshdirect beef for tartare? (or other sources)
I recently tried Florent Meat Market on Jones Street in Greenwich Village to get short ribs. It is a very small place and reminds you of the old time butcher shops. It was facinating to watch the butcher cuts the meat right in front of you and ask how you want your meat cut or how you plan to cook it and will offer suggestions. The meat was very high quality and reasonably priced. Give them a try!
