Foodspot recomandations (budget)

Hey peoplesss!

We are heading to Florence from July 14th till July 16th. Are there any secrer foodspots or must-see restaurants or bars?

We are on a budget trip, so sadly no big priced nultiple courses meals! So what I am looking for is a authentic experience and trying as much food as possible! :)

Would love to get your experience and tips!
