Everything about Portofino is unassuming: its quiet location in Zinkensdamm, its nondescript brick exterior, and its short menu, which offers five appetizers, five primi piatti entrees, and four main courses. But this simplicity is part of the restaurant's success—and one reason it's a favorite of celebrities such as Beyoncé and Benny Andersson of ABBA. The decor consists of dark leather booths, yellow chairs, dark wood tables, and candles. Focused on on classic Northern Italian dishes, the menu includes veal carpaccio, mushroom cannelloni, and panna cotta, while the signature dish is fettuccine portofino made with veal fillet, truffles, and baby spinach. The chocolate cake is accompanied by lingonberries and mint sorbet.
