Many chain restaurants, both fast food and upscale, from the United States are present in Aruba i.e. Texas de Brazil, Wendy's, Burger King, Taco Bell, Pizza Hut, Hooters, Subway, Tony Romas. You'll find some downtown, and many near the large resort hotels.
The upscale restaurants near resorts vary in quality as there are a limited number of them and they have a steady stream of tourist customers, as they advertise in pamphlets available in the hotels. The fast food places are essentially no different than their American counterparts.
Also good are some of the local fare restaurants. While obviously relying on tourist income, good food can be had. Nos Cunucu is a good example of such. With meals like the traditional baked cheese and some more interesting items such as Iguana soup. Don't be afraid to eat at random bars and such along the road, with normal caution of course. Good food can be had for relatively low cost. These pander to locals.
