My boyfriend and I managed to catch Mission Mahi at a food truck round up at the Pittsburgh Public Market. Gyros N'At was unable to make it but we've been trying to grab Mission Mahi so it worked out.
We both gobbled down our taco before I could grab pictures. They were excellent. I really wouldn't call them tacos though. Some other people posted pictures. They're more like a pressed wrap, or a burrito than a taco, but that doesn't matter because they are packed with mahi mahi and flavor (and they have sriracha mayo - it's on most of their tacos). I got the Greek and my boyfriend got the Tex-Mex. They were really flavorful and filling. I was surprised by how much fish there was.
They were out of fries when we were there, but I ended up full from just the taco. My boyfriend grabbed a side from one of the other food trucks.
I defintiely would recommend Mission Mahi. They're going to be at Voodoo Brewing for another food truck round up later this month and I might need to have them again.
