Eh, nothing that special. The food truck was in our parking lot. Read a lot of good things about the fries but they were out when I got to the truck so I got the box combo with macaroni salad. The mac salad was good. Pretty basic but good. I got popcorn chicken with the raspberry chili sauce. Popcorn chicken were good (they aren't shy with portions either). I asked what the most popular sauces were between the raspberry, the Buffalo Bill, and the Feinberg. I wanted a good balance of heat to sweet. Not too much of either one. He made it clear that the Feinberg was definitely more sweet but that the raspberry was very popular and had a little more spice. The "BBQ" sauce was very thick, almost like the raspberry jam that's in it. I tasted zero spice but it was still pretty good. The wait time was what I'd expect for a good truck with only two people who are making a large number of guests, a large number of orders. If you don't want to wait, don't hit up a popular food truck.
People with experience of eating Sin City in the line were going on and on about the tenders. Also saw some really good looking (and smelling) onion rings come out.
Overall, I honestly wouldn't go spending my money here again. The staff were very nice but I'm not the biggest fan and my mind wasn't blown by these. Good but nothing special.
