The best burgers 🍔 🍔 🍔 between Helsinki and Ankara !!! This restaurant deserves 10 out of 10 points. Forget all the fast food companies you know - "Fast 66" is the real deal! The buns are fluffy, the meat patties are best quality and spicy and everything is tasty and well seasoned, dependant on the Burger you choose. If you are a Hamburger gourmet, then don't miss it. The staff is very kind and welcoming to the guests - one of the most important qualities in gastronomy! Thank you, Fast 66 !!!

Excellent hamburgers ! Very nice people, had a good laugh with the owner. The food is very good, real authentic burgers for a low price

Best burger I have ever had! After a cruise I would stop for a bite and never have been disappointed! Every recommendation!!

Hey Folks, These Burgers Are just gorgeous!!! I ate burgers all over the world, but fast66 set a new Level. If you are in Labin or surrounding area pass by you will not regret!!! 6 out of 5 stars!!! Best greetings to fast66

One of the worst Burgers ever! The Buns are ok but lack butter when toasted but the patty is not enjoyable at all! It doesn’t taste good, is not well flavored and has no roasted aroma from being grilled well. And to make matters worse it’s desperately low quality meat and overcooked so it’s not juicy at all. Speaking of juiciness the whole burger isn’t juicy, lacks of sauce added, lacks flavoring. The bacon is not crispy and tastes horrible as well. Guess it’s because bacon is hard to get in Croatia but I bet it’s not as hard as it’s used to be in the past you just have to search for good quality. All in all I think the quality of the ingredients isn’t good. It’s very cheap and low quality to be honest. And I know what real good burgers taste like from American Burger makers. Even I would make a thousand times better burger, sorry to say that. I don’t understand the good reviews, I wouldn’t recommend just stay with traditional Croatian food!

Super tasty food, burgers are top notch, my suggestion is to try ROCK burger, place is cool AF and chef is amazing. Will be back 100% and would recommend everyone to grab adorable but tasty food

The high class burger experience :) Rock really rocks and Istriano is out-of-space, all spiced up with friendly atmosphere and great service. Definitely a must stop by!

Quick and delicious food. My family is visiting from the USA and enjoyed the cheeseburgers and fries. The service was good and the proprietor was friendly and helpful, giving us tips on other places to visit in Croatia!

The best burger in Europe. We came here after reading a review claiming this place served the best burger in Croatia. I disagree, it was the best burger I've eaten in Europe, possibly the world. The 2 guys running the place were friendly and funny, and the joint had a nice ambience. But the food! OMG, it was amazing. I had the Rock Burger and fries, my partner had the Cheese Burger and they were out of this world! The patties were tasty and succulent, the bun was soft and fresh, and chef's special sauce was divine! A burger is a simple meal and much depends on good ingredients and the care with which it is put together. Believe me, you can taste the love in the burgers at Fast 66. Nobody does it better.

Great fast food dinner. The only reason for 4 star is that place is really small and doesn't have lots of sitting places. But if you eat fast, that's not gonna be a problem 😉

Really remarkable food, great service. Bun from cheeseburger is awsome. Love it. ✅
