After years of going I guess I'm burned out. The festival basically is the exact same each year. If you've never been, it is worth the trip. Gone before? Maybe.
Highlights of the weekend:
A chance to show off some of the cooler businesses in old town Glendale.
Chocolate.
Some guys that come each year with homemade root beer (worth it for them alone).
OTG (one of the pubs) generally has at least 1 chocolate beer on tap.
Great restaurants in downtown Glendale. Haus Murphy and Pizza al Forno are two of my favorites. Lenny's is okay if you want a burger, fries, and malt.
Downsides:
Parking. All Glendale events have this issue. It's not awful, but not great.
It is the exact same each year. Unless you are a real chocoholic I'd say it is worth going once or twice. But after a while it's got a bit of that "been there, done that" feel. I don't know what would help but this year we basically just did a loop around and had some root beer.
Go once. Go with friends or kids. Hit up some of the local businesses. But I'm not sure it is a year in and year out thing.
