AMAZING. We have a similar market in Detroit, but this was nice because you don't have to walk through the ghetto to get to it. The prices are decent (maybe a little more than farmers markets by me, but the economy in Cleveland appears to be better too).
I went to one stand that had falafel and I am a snobby Arabic food person, but this was very good. The hummus was good also.
I didn't buy a ton because I had a stroller and was overwhelmed. If you go with a kid, bring a kid back pack. But otherwise, really great.
