Absolutely loved this restaurant; the food, atmosphere, staff and general experience was perfect. A group of around 15 came for a friend's 21st birthday dinner, and although the restaurant was small, we weren't made to feel out of place or in the way. The staff helped out with the cake and even 21st decorations for the night. It is a beautifully decorated space, offering different types of seating, with fairy lights and artwork, making it cosy, warming, relaxing, and romantic if you want it to be. The food was exactly what you'd expect from good old hearty Italian. Especially the cannelloni! It was in the medium price range for a bunch of students but you do get a lot of food and at high quality. Will definitely keep on coming back and recommending Cosa Nostra.
