This branch must not be called burger king, it's far away from burger king level. No worth eating there! I would like to mention something good but actually there is nothing. Horrible food! Beside this no good cleaning, WC smells like smoke. I don't recommend it at all, not even to drink something. If they want to save this place they need to restructure it at all level.

Big brand Burger King i was thinking that you have respect for your clients. Today o ordered King Beef menu with one Cola and 2 double cheeseburger with Fanta. When I reached the window the BK worker told me that he doesn't have Fanta. I wait at the Window 2 minutes and my order was ready no Cola in my King Beef menu and instead of Fanta we receive Orange Saft. By the way my King Beef Burger meat was like a Boot , dry and burned , was 100% not fresh done and no sauce in the burger No Cola in my menu how I ordered and instead of Fanta we received Orange Saft and instead of Mayo we received Ketchup So I payed 20 euro in total for a dry and burned meat without Cola and Fanta , but I payed for that ones Please review your employee Mr.Burger King the guy who take my order was not speaking good Deutsch also , I repeated everything from my order 3 times to make him understand If you want to have customers please review your employee because like this nobody will go there anymore!! This was Burger King respect for his clients!!!! Rheinfelden 11Feb2021

The staff is very good and nice and they helped us before closing in 5 minutes

The burger and the fries were very good. In my experience, burger king tastes much better in Germany than the neighbour countries, like Switzerland or Austria. And it's also cheaper and they always have special new burgers on offer.

The food has no tast ( the fries were like it not even in the oil for 30 sec the meat also tasted like it’s not cooked correctly

The best burger I've eaten outside in over a year

Well I have been couple times dinning in this particular establishment however always somewhat disappointed 😞, somethings missing or need to wait or just overall crazy customer service and this is my sincere easy going on BKs opinion, since I love BKs more than MCs

WERY POORLY KITCHEN HYGIENE , I got infected with Staphylococcus aureus bacteria. This comes from poorly staff hygiene from hands and/or open wounds. I ate with my family at Rheinfelden BK. Husband and I had double whoppers with cheese and bacon, kids chilli cheese fries and king wings. My husbands whopper was so "wet" it had like water running out of it, but the worst was that within 3 hours I got so sick. I know it was the food who got me sick, as its all I had to eat that day.

Well,it's not bad at all for lunches or quick snacks,but I find it not as little children friendly but for the big kids awesome...and their food tastes good ,and the prices are unbeatable.

Easy access to the Biel train station, just across the street. Get deals if you download the Burger King app first.

The (Vegan) food is good, the restaurant is clean and personal is friendly.

I normally like Burger King, but this branch is far below its usual standards. It smells like old used oil in there, and the food isn't as good as it should be. I don't know how they manage to do that. To top it off, they have some impressively unfriendly staff there. Avoid and just go to the competition down the road.

With all due respect to all the comments, Burger King has the best quality of meat and burgers and offers the best burgers, but when you order your order, you are late and come to us. This is your fault. In fact, unlike the entire staff, they are at your service. We strive to always serve the customer and the food is always fresh. As for the bathroom, it has been modified and we apologize to everyone.
