The museums along Via Garibaldi are known collectively as the 'Musei di Strada Nuova' - the individual buildings are the Palazzo Bianco, Palazzo Rosso and Palazzo Tursi. You have to buy your entry ticket (valid for all three) from the bookshop between Bianco and Tursi before trying to enter any of the museums.
The Palazzo Rosso is a beautiful building just to wander round. The rooms are quite rough but it has a definite atmosphere. There is an excellent collection of art, including artists from Genoa.
There's a very good cafe on the ground floor - top value, and free wi-fi!
