Sarotti Höfe is a hotel on Mehringdamm (Kreuzberg) and offers a great Brunch buffet on Sunday mornings. For 14,50€ you get access to the buffet and a glass of Sekt/Prosecco.
The food offer is pretty wide, from hot to cold, from sweet to savoury, meat, fish, cheese, ham, vegetables, croissants, bread, butter, jams, nutella, cereals,… You’re almost sure to find something that suits you. There’s also free water and orange juice available. All hot drinks come extra, I can highly recommend hot chocolate, one of the specialty of the place, Sarotti being a chocolate brand.
The place is cosy, there’s a small terrace outside, which can be nice by sunny weather. The staff is quite friendly. One important thing, it’s better to book in advance, the place is often packed, even if you’re just 2 or 3, give them a call before going there, just to be sure.
