Verdict: Fast, affordable, and authentically Japanese, Mos Burger is my favorite burger chain in the Brisbane/Gold Coast area next to Grill'd (http://www.yelp.com/biz/grilld-healthy-burgers-st-kilda-2), and you should absolutely give it a go. This needs to come to the US!
Star 1: How was the service and atmosphere?
With a fast, friendly, and authentic staff, Mos Burger is quick and easy regardless of where you're from thanks to the simplicity of their menu. With roughly 16 or so staple options that span Beef, Chicken, Lamb and Vegetarian, just point to what you want and you're good. Star Granted.
Star 2: How were the portions relative to the cost?
With $10 being the average price for even a quick meal out in Australia these days, it's a huge relief to see a menu at Mos Burger that's so affordable. No, the burgers aren't huge (roughly equivalent to a McDonalds cheeseburger), but at prices ranging from sub-$5 for a regular burger to only $7 for a double patty burger ($9ish for a full combo meal), Mos Burger is one of the most affordable options in the area. Star Granted.
Stars 3 and 4: How was the food?
Without a doubt, Mos Burger has some of the most unique and tasty options I've had at a fast food joint. On my first visit, I decided to go with the Spicy Cheeseburger, which was very good thanks to a unique spicy sauce.

However, I was in for a real treat on my second visit, where my Kimchi Beef Burger on a rice bun was unlike anything I've ever had. Properly spicy, the sandwich was excellent, and the rice burger bun was fantastic.

Finally, on a third visit (yes, I went on a Mos Burger rampage while in Australia), my Teriyaki Chicken Burger was excellent. Honestly, it's hard to go wrong here.

Dual Stars Granted.
Star 5: Would you eat here every day if you could?
Yes! While I'd always crowned the United States king of the Hamburger, the rest of the world really is catching up, and fast food chains such as McDonald's and Burger King better watch out if Mos Burger arrives on US shores. It's no wonder Mos is the second most popular burger chain in Japan behind McDonald's. Star Granted. read more
