With so many events happening in this city every year, when one continues to come back around and can still impress, you know it’s a winner. I’ve attended East Passyunk’s standout spring food festival, Flavors of the Avenue, the past two years and loved every minute (and bite). Like last year, I was able to get a sample (or several) of the action before this year’s event, and I’m excited to share with you what you can look forward to later this month.
