The "Lubi"
Lubi is a Jacksonville original, a steaming sandwich of ground sirloin, mustard, mayonnaise, sour cream, pepper sauce and cheese that is so gooey you have to eat it with a knife and fork.There are only four places in the world where you can get a Lubi, and all of them are on the First Coast.The sandwich originated at a family-run restaurant started in 1969 by Lu and Bill Wallace as a side venture. The couple's main business was an ambulance service at 2940 University Blvd. W. When the front part of the building became vacant, Lu thought it would be fun to open a small sandwich shop, which they called Lubi's (a combination of the couple's first names).
