This was my first time attending and I can't say I was dissapointed but it was lacking something I can't put my finger on. The food vendors were certainly a mix but the food being offered at most were mundane. There was an exception here and there like E2's tent. That was probably the best deal out there with the sliders they had for 2 coins. That's the other thing, $20 get's you 15 coins and most everything is at least 2 coins except the beer, that was 4. My suggestions is drink before hand. The beer selection is certainly nothing to rave about, maybe next year they can combine this was a craft beer side or something.
Either way, it's great people watching and it gets crowded so be prepared.
