Was here four years ago and was very excited to go back a few days ago. Yes. It's a touristy thing--fries and cole slaw ON the sandwich?! I wish it was the standard, and not so much novelty.
The corned beef was great (I just wish there was more), got a fried egg on it, and I was very content. The bread was great, the cole slaw was tangy, the fries were a little soggy for my taste but they work great on the sandwich.
I'd be back. Next year, in Pittsburgh.
