Osso Pasta is an Italian home-style pasta restaurant in Seoul. Its menu changes weekly, with dishes such as squid ink spaghetti and tomato basil pesto pasta. The restaurant is run by a couple who lived in Italy for a long time, posts its weekend menu on Instagram every Wednesday, and takes reservations by text message. It opens only on weekends by reservation, so you have to match your visit to a day when the menu you want is served.
