People visiting this Hungarian bar really get to leave their mark. Like any small business, a Budapest bar called ‘For Sale’ thrives off of customer reviews. But unlike most establishments, where patrons leave their comments online, at For Sale, customers leave their remarks on the walls. Since it opened in the 90s, For Sale has had a good mix of locals and tourists, though more and more visitors are crossing the threshold since the bar and its notes went viral on social media.
