The owners of restaurants in touristic areas are perfectly aware of the fact that you're a tourist. That means they think you've got money to blow and no knowledge of where to spend it, which means they can jack up the prices. Not to mention that after a long day of museums and sightseeing, you're likely to sit down at the closest place you can find, even though they might not be offering traditional, local food. So avoid eating in tourist areas right near historic sights and museums if you want to save yourself some money.
