Really? It doesn't get any better than this.
I grew up in Cleveland and remember going here as a child and being face to face with snouts...but after stopping for a pizza bagel I was happy. But seriously if you want fresh eats this is the spot to get them! Though you might feel as though you are in Europe from what some of the produce vendors' shout outs...but you can't beat the prices they offer for fresh fruit, greens, everything out there! Then head inside because I like to time it so I can have a crepe for lunch inside at Crepes De Luxe. I then take it out the doors to the right and upstairs where you can sit up top with a view of the entire market.
I recommend stopping at Vince's Meat G-6 for his Steak on a Stick. You may have to order and come back in 10min or so but it's well worth it. Pierogi Palace at E-5 is great...you can choose from a huge assortment on hand-always delicious. Ohio City Pasta also offers a great variety.
Honestly this experience is in the eye of the beholder. Take your time. Spend a leisurely afternoon wandering through the market-finding favorites and snacking on the variety this place has to offer! You won't go home hungry and your wallet will also thank you:) although...it is easy to keep spending and spending and spending...
