I don't know about other cities, but in Washington, DC, the pandemic lockdown essentially destroyed the food truck business. A few operate along the edges of the National Mall, where the customers must be tourists. But McPherson Square, Farragut Square, and L St. NW used to have a lot of food trucks and have none now. So maybe find a pretty outdoor area where there are lots of tourists.
