The bad reviews here are silly.
This is a snack bar at a public facility.
Provenance Cafe raises the bar well out of reach for FAR inferior snack bars at places like The Salvador Dali Museum in St Pete and The Met and The Cloisters both in NYC. There are so many actual food choices here, I've come solely to eat at the cafe on occasion. I like that they have healthy beverage choices too.
Someone mentioned the crowds...we should be so lucky to have nice crowds in Cleveland now. It's fun to sit at a table and converse with the folks at the next, who are more and more likely to not be from the U.S.
Get the swordfish sandwich.
