1 star for the fatal flaw in the entire idea of the event: Why are we paying $8 admission to get into a parking lot to pay for food?
None of this is the fault of the food trucks. I had many a great dish off the food trucks that participated in 2012 (I also had some mediocre food, but the imagination of the inventive trucks outweighed the food that was just decent).
But the good food just won't save the fact that the Foodie Fest is asking people to pay $8 to wander around a hot parking lot to choose something to eat off of a food truck. Not to wander around a nice green park or even a desert park--a parking lot. So the $8 buys the right to walk around the parking lot with no central entertainment--it's not a Renaissance Fair with food or a music festival with food--it's just a parking lot with food and a carnival parked next door (maybe that's a lure if you have a lot of kids).
Look I love food truck culture, but I still can't figure out why there's an admission price. And a note to the trucks: if people are paying admission to come try out a bunch of dishes, change your menu up and offer small dishes for cheaper prices. Most of the trucks were offering a full dish for $7-10. Most of the time I love the larger dish, but folks came to the festival to taste as many things as possible (for $8 admission). Trucks participating in the event might want to offer small "tasting" dishes so that fest-goers can try out more trucks and more dishes. The way it worked out this year, I split 5 dishes off of five trucks and just kept thinking "I really paid $8 to walk around this parking lot".
Food: great to good. Music: meh. Atmosphere: awful. Admission price: ridiculous given that you're not getting anything with admission.
