I eat here every time I'm in cleveland. Open 24 hours a day, with deli sandwiches that take the best Columbus has to offer and breaks it over its knee. The Rubin is hands down the best you will ever have. I also really enjoy the Rocky and their club sandwich. Great fries.
Do yourself a favor and go... on the other hand one trip there will leave you disgusted with almost every other deli sandwich you will get form any other place. The pie selection is also great.
