I'd say its pretty casual. Very few people wear suit and ties anymore and even a sportcoat is fairly rare.
I've typically seen anything from t-shirt and shorts, to jeans, to khakis and a polo shirt.
Of course, it all depends on your age and part of the country.
To be fair, the gourmet food trucks are quite a bit better than the roach coaches that Pio is describing. And I've eaten from plenty of those and taco trucks as well.
I'm just surprised by how many hipsters are willing to wait in massive lines at these food truck festivals in both California and Arizona recently.
But yeah, the Twitter thing probably has something to do with it as well (and Yelp loves them as well). It's like you have to be in a private group to know...
Along the same lines, what's with hipsters waiting in line for food trucks... and the love of food trucks in general?
The 4th Sacramento Mobile Food Festival was today and once again, thousands of people showed up to wait in line for hours to get food from the various trucks. I attended the first one last year, but left when I realized that it would take up to three hours to get anything to eat.
I've tried a few of the local trucks when I've found them and while they are...
My favorite, go-to, blue blazer is a standard two button jacket with flap pockets and single vent made by Brooks Brothers from Lora Piana wool.
However, I swapped out the standard BB buttons for my own gold, monogrammed buttons that I bought 20-years ago (this is the fourth blazer they've been on).
The fabric is a nice year round weight and the style can be fancy or casual depending on what I pair it with.
