I am a HUGE fan of this truck. For the longest time, it was like my White Whale; I saw it pop up on Twitter but could never find it in real life. I finally (!!) pinned it down at Coffee Buddha one day and have been hooked ever since. My mouth is watering just writing this!
Sure, it's a little on the expensive side for a food truck, but you get quality and quantity, my friends. The menu is pretty big and they only have certain items on the truck, so be sure to follow them on Twitter to see what their offerings are. Even if you don't see your favorite, go eat there anyway. The burgers are fresh, always piled high with amazing toppings, and so juicy you will need to roll up your sleeves. Now let's talk about the fries. You get a ton of fresh-cut, warm, salty fries. I'd liken these to Winghart's and are currently tied for "most favorite fries in Pittsburgh."
I'd go for The French Lieutenant's Burger and Curly's Truffle but they usually have a special Buddha Burger when they're parked at Coffee Buddha. Go. Run. Now!
