The Taste of Charlotte occurs annually around the first weekend of June. It's described as, "The area's Largest Food Festival. Enjoy an array of culinary delights as you choose from over 100 samples from Charlotte's Finest Restaurants."
What it is is a miniaturized version of the annual fall Food & Wine Festival at Epcot without any of the international scenery. Plus, the event is crammed onto both sides of the street down Tryon St in Uptown Charlotte (not even utilizing the sidewalks). Imagine 150,000 people trying to walk up and down one long strip in the middle of the hot summer. It ain't pretty. Plus, while the idea of sampling different foods from various restaurants sounds appealing, the catch is that the booths actually have to HAVE the food that claim they're offering. We went early in the evening on a Saturday night and a lot of booths were already "sold out," so we couldn't sample most things we even wanted to.
Additionally, out of over 100 booths, there were only 3 or 4 small booths where you could buy beverages. How were the lines at these booths? Did I mention it was hot out?
My recommendation to the event crew would be to take a trip to Florida, visit the Food & Wine Festival at Epcot, and see how it's done. Then come back to Charlotte and put on a really good show.
