The one thing that I wish I could bring to the JFX Farmer's Market is a little more breakfast food options. I am the type of person who loves breakfast and I never skip it. On one of our first trips down there, we decided to hit up the Ruben's Crepes stand, since they seemed to have a long line and a lot of breakfast-y choices.
I loved that you could see the workers making everything right in front of you and that your crepe came to you fresh off the grill. I got one that was a bacon, egg, and cheese and G got one that had pepperonis and mozzarella. They were both really tasty. The crepe serves as a nice alternative to toast or a muffin and everything tasted very fresh. Everyone there was friendly and the food was somewhat portable for walking around the market. I can't speak for their location in Federal Hill, but I assume that they have to be equivalent. All in all, it's a nice place to get your fix at the Farmer's Market!
