Whenever I'm in a food court, which is quite often, my number one pick for lunch is Opa Souvlaki. I always order the chicken pita, with the works (yes even the jalapenos).
The thing I love about Opa is the consistent good service and the fresh ingredients. I like watching the cooks grill my chicken and put together my meal. Even though it's a franchise, all the Opas I visit feel like mom and pops places where they care about your business and want you to come back.
The two Opas I visit the most are in Market Mall and Northland Mall.
