My introduction to Porky's was at lunchtime on a weekday, so not crowded at all. HOWEVER, although there were many food trucks, there were only 2 or 3 open. After observing sizes of food items, DS and I decided to split a burrito and I got iced tea while he opted for a beer. I still could only eat half of mine, so I took home the rest for lunch the next day. 3 MEALS from one purchase made it doable.
DS & DH went on a weekend during a big sports TV event. MOBBED! I dropped them off and picked them up rather than them trying to find parking. They had a blast!
