West Side Market is one of my favorite places to go to, and although that might sound silly because it's essentially like a grocery store (but way more awesome) I can spend my whole Saturday roaming around the isles of the market. If I ever were to move to Cleveland I would make the market my one stop shop for all my food needs.
I have to say I'm very jealous of those who get to do so!
What I love most about West Side Market is the atmosphere. Everyone is friendly and willing to let you try anything before you buy. The reason they don't mind is because you probably will be buying it! Everything is DELICIOUS!
If you go, you have to get a gyro from Steve's Gyros. It 100% lives up to the hype. I know once you see the line for the stand you might be turned off, but be patient! You won't regret it. I myself am not a huge gyro fan but I would not hesitate to get a gyro from Steve's.
West Side Market is going to have something for everyone, so make it a day date with your best friend and head out!
