They gave out some hot drinks for those waiting in line outside in the cold. Food: 5/5 I got the banana pudding matcha and chili eggs on toast. So good! You can taste how fresh everything was. Would definitely come back i the future to try other items.

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.

Mr. Clou is one of those well needed vendors when traveling for refreshing cups of fruit, juices,…read moreyogurts, a light bite, a detox drink, etc...I came here twice on getting off and going back to the Frankfurt Hauptbahnof and each visit provided a refreshing serving. Might I point out that it's affordable for only about less than or above average price of 3 Euros as a simple serving. They have stool seating and tables, which is a but rare for the rest of vendors don't have such. The staff seems alright, not super friendly but cool enough. I didn't detect anything nasty, just couple guys doing their job and serving fruit. There's also an Express version of Mr. Clou by the entrance but this is the one in front of the Dunkin' Donuts.
