Depends on the local market.

Assuming you go to a good food truck, my experience with food trucks is GENERALLY that the food quality is as good as a high end restaraunt of the same type (because they only do 2 or 3 things) but with slightly lower prices however its still noticably more expensive than a “pretty good” item from a “pretty good” restaurant.

Like… your getting a 9/10 for 7/10 prices, but you can get a 5/10 for 5/10 price anywhere.
