Just to clarify (and I promise not to stay on a soapbox) I think the food truck was an attempt to reach an audience in my generation and younger (12th anniversary of my 29th birthday) rather than my parents generation, especially with OneSpark events starting next week.
There are actually several nice restaurants in close proximity and about 5 under construction nearby (several investors have been pouring money into rehabbing post fire era buildings downtown and Brooklyn which is the neighborhood next to downtown). Jacksonville is a bit weird, being the largest city land-wise in the continental US, so where for most other places would have a separate* mid size town nearby but in the same county, those are higher density suburbs within the city limits here and typically have their own cultural "heart". *except the beaches, where the city of Jacksonville acts as the county government for them.
I am sure I will be corrected if I am wrong, but I believe we are the only city in Florida, and one of the few in the south, that has a dedicated symphony hall.

The symphony hall is in the same building as two performance stages, one larger I.E. for Wicked and one smaller with events almost every day.
