5 U.S. Dining Destinations You Must Visit

While many adults 50 and over choose to visit the beach, take a cruise or explore Europe during their vacations, some are looking to take the road less traveled and are literally putting their money where their mouth is.

With more disposable income than previous generations and a love for the culinary arts, adults 50 and over are expected to spend upwards of $120 billion on leisure travel in 2015 and choose vacation destinations based on the cuisine of the region and not the local attractions. Called food tourism, travelers look for memorable eating experiences when choosing where they would like to vacation.

A recent survey shows that 27 million Americans engaged in culinary activities while traveling. These culinary activities ranged from dining out to visiting farmers' markets to taking cooking classes. The survey also found that the average food traveler spends $1,271 per trip, with 50 percent of those funds going toward food-related activities.
