I feel like perhaps I should share my system for finding good local restaurants when traveling. I assure you that the system always works and that this is not a joke. When I told a buddy of mine about it he assumed I was just being funny, then he saw it in action when we went to Memphis and it lead us to an incredible local barbecue place.
So what you do is scout for a reasonably well dressed fat woman. Not morbidly obese fat or you're just going to get a buffet, but fat enough that you're reasonably sure she'll get winded on a flight of stairs. Nobody under 30 or over 50 years old. Nobody with children in tow. If possible, someone without a wedding ring, but if it's a low target environment you might have to go with a married fatty. The manner of dress isn't as important as the apparent value of the clothing. Someone dressed like someone who'd date her could afford the sort of restaurant you're interested in. She must, of course, be local and not also a tourist. Once you've spotted an appropriate fat woman, simply approach with a "pardon me, Ma'am, we're from out of town and was curious as to a good local restaurant." sort of line. I generally don't specify what type of restaurant so as not to pin them down or make them search their memory. I want their gut instinct (so to speak).
I have done this in multiple states in multiple countries and it has *always* worked out well.
