I've been told that Petra Palace in Itaewon is home to Seoul's finest falafel, and as a huge fan of Middle Eastern cuisine, I knew I had to swing by and give it a try. The outside announces that Petra Palace offers "Authentic Arabian Dining" and "100% Halal"--definitely pluses, but honestly all I cared about was if the food was good or not. Thankfully, it was. Considering the lack of falafel in my life when I'm in Seoul, Petra Palace is a godsend. It isn't the best falafel I've had in my life, but it was certainly decent and tasted exactly like the falafel that I'd had before, rather than some strange sweetened Korean version (which happens often to non-Korean food here in Seoul). The hummus was delicious and light, and the servings of pita were incredibly generous.
The menu selection at Petra Palace offers a lot of goodies that I haven't seen around: baba ganoush, for one. For starters, though, I recommend the falafel platter and one of the meat/hummus platters, which should be good for about two servings' worth of food. The prices, too, which ranged from about 10,000 to 15,000, weren't bad at all considering the portion sizes.
