I've been here 3 times since I found out about it last week, and have recommended it to others who have also loved it! I'm Turkish so I'm always looking for quality Middle Eastern or Mediterranean food and I love Mashawi.
My favorites are chicken shawarma sandwich and the regular beef/lamb shawarma sandwich (in Turkey we call them doner :) But I have many more items I want to try, especially the veggie items.
The prices are also amazing! I can easily have dinner with a friend for under $10 total, which is great on a busy evening. The owner and staff are super nice and friendly, the owner spoke a bit of Arabic with me and gave us free baklava on our first visit, which was very kind (and delicious!)
If you like Layalina, you should try out Mashawi Grill!
