We came on a Sunday and it was packed. NOTE: They only serve Iskander from Fri-Sun. So it's very packed on weekends. We didn't want to wait an hour so we came back on a Monday to try their Pide and beef kebab.
I thought the beef kebab was just ok. It's basically tenderloin beef chunks with a light tomato based sauce with rice, some veggies, and a salad. But for $20 I would be just as happy to order a similar beef steak/tenderloin kebob from other middle eastern places for around $14-16.
Now the Pide (and Iskander) seems to be what people are raving about, and rightly so. The Pide is noticeably more pricey than Mr Pide's, starting at $12 and go to $16. Compared with Mr Pides which is around $10 each. However, this is a situation of you getting what you paid for. Mustafa's Pide is loaded with stuff. We ordered the lamb & mozzarella and also a ground beef Pide. Both are stuffed with tons of meat. And of course, they tastes fantastic. The dough is cooked just right and the meat are delicious. I'm no Pide expert but I'd say the meat to dough ratio is perfect!
So I would definitely come here for their Pide and Iskander. While I don't find their kebob dishes special, they are definitely delicious too.
