Gazpacho in downtown Baltimore?
I finally found your original request--don't know if it is within walking distance of FedHill--but Jack's Bistro serves gazpcho.
If you get the urge to not walk and travel a bit, Tark's in the Greenspring Station, along with the Milton Inn in Sparks, both offer gazpacho.
Too bad that gazpacho isn't offered more frequently in area restaurants, especially in the summer months. It's such a refreshing "soup"--and takes the opportunity to incorporate the best of the summer harvest of fresh vegetables--add some lump crabmeat on the top of the "soup"--Divine! FoiGras
