Finally tried this food truck at the Vegas StrEats Festival in Downtown LV after hearing so much about it, and I definitely agree that they make some damn good burgers.
I tried the Fuku-burger and it was cooked to perfection with some great flavors. It definitely has an asian flair to it. I also tried their garlic fries, and I would say that it also tastes amazing, and it complements the burger nicely.
The price is awesome, as I only spent $9 on a burger, fries, and a drink (unlike some gourmet burger places that will run you up close to $25 dollars for the same type of order).
The menu isn't complicated and I am looking forward to trying some of their other burgers. Oh, and if you tip them they give you this asian jelly treat and yell out "Tip Jelly!"
