This is a no brainer:
The Royal Warsaw
871 River Road
Elmwood Park, NJ
Check the site......I recommend the Beef Tartar.....double size of course.
It located just south of Routes 80 and 46 on the left
Be sure to check out Piast down the road about 0.5 miles south in Garfield, for some great $5 lunches, deli provisions and butchered meats. I recommend the Pork Shank and Kielbasa
