There's a lot of great food in Cleveland, and there are certainly a lot of great delis...and there is a lot of good corned beef.
Everyone here knows the top spots. In my opinion Corky and Lenny's is top 5. It's an institution that has been around for a very long time. You can get all of your deli favorites, great service, and sometimes with a side of attitude if you like.
Maybe I'm a little biased because this is the spot where I was introduced to the big corned beef sandwich as a kid, and returned to in high school and college with my boys when grabbing a bite after a long day. A little biased, but not much. These guys have earned their position among Cleveland's best.
