Absolutely.
A local place by my house called Franco's turned me on to the balsamic and parmesan thing.
When making a salad I usually throw slices of parmesan on top, I prefer the white balsamic and of course extra virgin olive oil. Don't even get me started at that, I could take a bath in olive oil.
PhillyQ, you are so right about the search for some good mozzarella being worth it.
Moving from the east coast to out west we suffered for years without it, thankfully now we have some high quality Italian delis and grocers.
