Here is a tip I learned the hard way.
Take photos of the name of every restaurant you eat in when you travel. Not only will it help you remember the name of that great little cafe in Rome where you had the best linguine vongole of your life four years ago (my story), but it will also help you remember the name of the that terrible and over-priced restaurant that you want to tell your colleague to avoid on her honeymoon trip (also a true story!).
Take a photo of the front of the restaurant, the menu, the napkin, their business card and keep it with your vacation photos. I promise you it will definitely come in handy!
Whenever I travel I now religiously make sure I document every restaurant name with a photo (if you forget your camera, use your smart phone).
Now…about that darn restaurant in Rome….
How about you? Have a similar travel tip to remember places that you visit?
