Very good museum - dont miss the cafe terrace with good views over Rome - reasonably priced coffee and sandwich for lunch. Some worthy exhibits - there are a lot of rooms so use an audio guide or a guide book to find the treasures of the museum and skip the more mundane busts of various emperors. The museum is split in two and the other half is reached by an underground passage so dont miss this bit out. Halfway along this passage is a corridor and some stairs that lead to the Tabularium at the back of the Capitoline Hill with stunning views over the Roman Forum.
