Taormina is a resort town. One should know this before arriving there. Things are usually more expensive in resort towns and when one is as beautiful and beautifully situated as Taormina is, then one needs to expect the higher prices. But if you do a little homework beforehand you can eat well for not much, the admission charge to the Greco/Roman theatre is small and the spectacular views from the many terraces and the immaculate public garden, etc., are free! Paris is a tourist trap, Rome is a tourist trap and Venice is definitely a tourist trap...if you don't use your head. Travel smarter, you'll complain less.
Unique Suggestions: See above...
Well Taormina is a very popular touist area and they know it. The prices are very high here. Four post cards cost me €2 where I could get up to 8 for that price in Malta and most other places. Food is also very expensive. A woman in our group bought a piece of lasagna at one of the cafes. It and a glass of beer cost €9. Later when we stopped for dinner near Nicolosi she once again had lasagna and a beer and it was only €5 and looked much better and was twice as large.
Unique Suggestions: Just know ahead of time things are going to cost you more in Taormina and budget for it. If you know in advance getting gouged isn't as bad as it is when its a complete surprise.
The entire Taormina is one big tourist trap but one of those so very justifiably so.
Unique Suggestions: Avoiid eating along the Corso Umberto and instead, follow the locals to restaurants further down towards the bus station or elsewhere outside the hub of it all. You will be rewarded by a much more relaxing atmosphere and a smaller bill.
