Here is a summary of the festival.
Positive:
1) street parking available within 3-4 blocks;
2) lots of food;
3) lots of vendors with expensive stuff;
4) drink ticket booths are throughout the festival;
5) no cover charge.
Cons:
1) few booths actually have anything with mushrooms. I chose rice with mushrooms, and it was good, but I expected lots of different dishes with mushrooms at a mushroom Mardi Gras;
2) premium wine tasting is a joke. You can get a Groupon a few bucks off the tasting, buy on their Facebook page or on site with cash. $30 gets you 10 tastings. Only those who bought the tickets can go in, but if there are two people in your group, you can buy one punch card with a "complimentary" festival glass and just alternate who goes in (as long as you ask for the wrist band for each person). There are 4 wineries; each offers 2 reds and 1 white. Not a great selection, but wine is great.
3) everything is extremely overpriced, but I guess this is a festival...
4) few things to pick for a vegetarian. You'd think at a mushroom festival that would not be an issue, but it is.
5) some vendors are a bit annoying trying to cover you with their cream products without consent.
Overall, a bummer, don't think I would go there unless I lived nearby.
I wasn't even motivated to film, because there was not much to film, but here you go...
