Very different events. To be honest, the food is going to be better and more interesting at the Randolph event, which is much slicker and professional. But for my money, the festa is the way to go. The neighborhood and the vibe are tough to beat. It's a very old-fashioned event. Lot's of Ital-American kitsch (resin Trevi fountain and all), but in a good way. And the food's not affirmatively bad by any means, sticking to street food such as grilled suasages, pizza, etc.
