Fries inside a gyro can sound like a stunt if you have only seen them treated as a side. In a Greek-style gyro, they have a job.
They bring heat back into the wrap after the vegetables and tzatziki go in. They add a little crispness so every bite is not just soft pita and sauce. They also soak up some of the juices from the meat, which keeps the gyro from falling apart too quickly.
At Love & Pita, the fries sit with the marinated chicken or lamb and pork, red onion, cherry tomatoes, tzatziki, smoked paprika, and toasted pita. The idea is not to make the gyro heavier. It is to make the whole thing feel complete without needing a pile of extras.
If you are ordering for the first time, start with the gyro as built. That is the version the menu is tuned around.
