I was treated to lunch at Sittoo's earlier this week. It's a clean, bright space with friendly servers, cheap prices and delicious Lebanese food. I had the falafel sandwich and really liked it. I wasn't a fan of the pickles-- but I never am, so my bad for not asking to have them removed-- but the falafel itself was delicious as was the pita and the lemon tahini dressing. It was a little on the small side, so if you're very hungry I'd suggest getting a side dish too. My table-mates both ordered the business lunch, which looked awesome and was definitely a steal for the price (three kinds of meat, salad, rice, and pita).
I'd definitely be a regular if I lived in Parma.
