The Best Reuben...

[Village Idiot]

I'm a sucker for a good rueben.

Mine is at the Broad Axe in Hagerstown.

Mine was at a little bar on Case Western Reserve's campus in Cleveland, OH called The Big Penny. The fries were pretty amazing there as well.

Unfortunately, now it's a (somewhat decent) Mexican place.

My favorites are at the old school delis:

Attman's in Baltimore - http://www.attmansdeli.com/

Katz's in New York - http://www.katzdeli.com/

New York has or had the best Reuben's but that being said...

Harold's Deli both the location in Edison area and Parsippany are out of this world awesome. The sandwiches are taller than a building, oy, ok I exaggerate... but you could plotz from the sheer size of them! We usually share 1 sandwich and take half home and eat it for 1 or 2 more meals together, if that gives you an idea. You can google them and see incredibly large sandwiches, desserts and more. Do NOT eat before you go and I strongly advise fasting at least 18 hours before you go there so you can try one of every good thing on the menu with or without sharing it.
