If you like cevapi and Burek, you need to try Mrakovic's food! I love their cevapi and cheese burek, and have ordered it to go many times. Unlike Royal Meats, they are reasonably priced ($10 for 10 cevapi, bread and kajmak).
They have a nice selection of food that you can order to go, or to eat in their small seating area. (It is like a small diner or cafe). They have cevapi, hamburgers, burek and other Bosnian foods.
You can also buy 50 or 100 cevapi that are frozen for barbecuing at home. This is a great option if you are having a family barbecue.
