I went to the Primanti's on South Side for lunch on a Monday. I actually wasn't planning on going to South Side, but I got lost navigating through Oakland and ended up on a bridge. Typical Clevelander trying to navigate the burgh. Figuring that I had to at least try this Pittsburgh tradition before leaving town, I stopped by.
Service was prompt and on cue. I ordered the cheese combo sandwich which was two slices of thick white break containing a mound of cole-slaw, large-cut fries and melted cheese.
The sandwich was ridiculously large as expected and very filling, though became kind of overwhelming after a few bites. The taste was good, but nothing to write home about in my honest opinion. I personally find that the large amount of coleslaw kind of overpowers the sandwich. The bread got soggy pretty quick and became less appetizing by the minute.
Who knows, maybe you'll enjoy it? Give it a shot if you haven't experienced it before. Just wasn't quite for me.
