I was really surprised to enjoy Bar Symon so much! It was exciting to me when this opened (and became a priority pass lounge in the airport so $28/person is covered if you have priority pass!) and it didn't disappoint. This is hands down the best airport food in CLE and one of the best airport restaurants I've been at.
The beer and cocktail options are quite varied, and the prices (while airport pricing) are not too bad with beers around $7-$9 and cocktails maybe around $13. Try Michael's Mule!
There were also a surprising number of vegetarian options and while I was skeptical of getting just a salad, the chickpea salad was huge and very filling.
I'm looking forward to my next visit to CLE so I can visit again!
