The salty brioche bun , came with scrambled eggs, chicken bacon, strawberries and maple syrup. It was the perfect combo of sweet, salty and savory!! The fried egg and cheese on brioche bun, was pretty good too. It came with a salad mix, and avocado but it wasn't as special as the salty "brioche bun". The vibes of the restaurant was very cute and open. It's a great place to just get a coffee or a quick bite with friends. They also offer outdoor dining and take card payments.

Had a layover and decided to try this restaurant.

Both hit the spot and were what we were looking for. Definitely more expensive than outside the airport but what can you do. The service speed is not bad despite being quite busy. Every small table was full. If you have a very short connection I would suggest grabbing a sandwich to go elsewhere. The only lounge in this part of the airport (Terminal 1 section B) is before security, and so we chose not to go to a lounge and to come here instead.

When a Manager Becomes the Reason to Leave a Restaurant!…read more Our visit to Sunny Side Up was unfortunately one of the most unpleasant restaurant experiences we have had in a long time. We stopped by for breakfast before leaving Frankfurt and had already placed our order. I was carrying a paper bag containing a muffin from another shop. The muffin remained in the bag under the table the entire time. I neither ate it nor took it out of the bag. A young man who introduced himself as the manager then approached our table. Instead of addressing the situation politely, professionally, and discreetly, he loudly confronted me in front of other guests in an inappropriate manner. His attitude was aggressive, condescending, and disrespectful. Of course, a restaurant has every right to set rules regarding outside food. No one was questioning that. What was completely unacceptable, however, was the way he chose to treat paying customers. When I explained that I was not eating the muffin and expressed my concern about his behavior, he showed no interest whatsoever in resolving the situation constructively. On the contrary, when I said that we would rather leave under those circumstances, he essentially told us to go ahead. So we left the restaurant, leaving our already served coffee behind. In my opinion, anyone who treats guests in this manner is not suited for a customer-facing role, let alone a management position. Hospitality is not merely about enforcing rules; it is about treating people with respect, tact, and basic decency. His behavior reflected the exact opposite. What I find particularly troubling is that this kind of conduct increasingly seems to be regarded as normal. It feels like a reflection of a broader societal decline in courtesy, respect, and common decency. This is simply not how customers should be treated. The name "Sunny Side Up" appears to aim for an American-style breakfast culture built on friendliness, openness, and good service. Unfortunately, it remains little more than a façade. While the restaurant attempts to imitate an American concept, it fails at the very thing that defines it: friendly, professional, customer-oriented service! We left the restaurant disappointed and upset. Based on this experience, we will not be returning and unfortunately cannot recommend Sunny Side Up.
