I'm 55. I think there are about 3 things I have eaten in my life that are so so good, that I have planned vacation detours to go back because I cannot find a version of whatever it is anywhere near me that tastes anywhere near as good. My list is below. I am eager to hear your list (I will be doing some cross country traveling soon and may try to visit). I guess this is a little bit like "Best thing you ever ate in your life" from the food network, but not quite. OK, her's my list.
3) Pit Beef from a place called Chaps outside of Baltimore MD (I think its Aberdeen). There may be regional variants that are just as good, maybe not...I don't know. But I have been to Chaps and I can't imagine there is any place better. You can see the beef cooking over the fire in the kitchen. It's pretty basic. They cook it, slice it, and put it on a bun, and I don't have any idea how to replicate it at home (I tried once and it was a dismal failure), nor has anywhere else I have ever lived had something like this. They have lots of other stuff, but if at Chap's I'm not sure why you would get anything else unless you lived in the area and can go back a lot and want to mix it up.
2) New Have style pizza. There are several apizza's in the greater New Haven area. I lived near, and loved, a place in West Haven called Zuppardi's. A number of years ago I found a place in Chicago that did a very good version of a New Haven style pizza, but I don't know if they are still open. New Haven pizza is traditionally baked in a coal-fired oven (but I don't know if that is necessary for the flavor). There is no rim to speak of and the sauce goes nearly to the edge, it is thin (but not cracker thin, but thinner than NY), and charred on the bottom. More crispy than chewy. And it is so good and no one anywhere else that I have lived even produced a bad facsimile much less a good one. For all intents and purposes, you have to go to Connecticut. White clam pies are popular. I always got a red pie with anchovies and sometimes mushrooms and/or other vegetables.
#1 spot - Thrashers boardwalk fries in Ocean City MD and Rehoboth Beach MD. OMG, how can these be so good? I have read articles describing approaches to replicating them at home but they are no where near as good. It's just a fried piece of potato but it is so much more. I may request that I be buried, or cremated with a basket full. Salt and vinegar only, no ketchup with these fries (and I have been accused of being a ketchup glutton). Do yourself a favor and cancel that trip to the Bahamas. Go to Ocean City or Rehoboth beach instead and visit Thrashers. If you go during beach season, there may be a long line but it moves fast enough. Besides, you're at the beach. You got somewhere to go? If you go during the off season, they may not be open. They have an extensive menu of small, medium, large and extra large as I recall. OK, they also have drinks (and I think I read that maybe they have hot dogs? but never noticed...again, why would you go to Thrashers and get a dog). You go for the fries!!
All of these places have websites. Bon appétit.
