Not long ago, I noticed a creeping trend in the city of steel. When The Goodie Truck rolled on to the scene a few years ago, I was ecstatic. It made Pittsburgh feel trendy in the food scene! But it stood alone, save the amazingly delicious Pad Thai truck that, for as long as I can remember, has served the heat from the corner of Fifth and Bigelow. Last year, the owners of downtown’s hip hot dog shop Franktuary took their meat to the streets. So I decided it was time to check them out.
