Re: “A modest little proposal for revitalizing downtown”

I am native of Rochester, but now live in Los Angeles.
If I were to send my friends/co-workers from LA to visit Rochester, what would you say would be interesting for them to see in downtown?
Another building?
Make Downtown Rochester a worthwhile visit, meaning a place of activity and culture. I think the "This Is not a Park" movement is onto something.
Food truck/vendor spots are big here in LA. People are drawn to what other people are doing/enjoying.

I think Rochester city planners should study cities like Pasadena and San Diego
