One of the joys of traveling in search of Roadfood is the discovery of excellent food in unlikely places. We've eaten well in bait shops, upholsterers, and a pistol range. I'm not sure what Sawasdee used to be -- convenience store? laundromat? gas station? -- and, by definition, it's not really Roadfood (Thai cuisine in Warrenville, South Carolina!); but I ate extremely well there and plan to return for more. The meal started with sensational coconut soup: creamy and coconut-sweet, vibrant with the fragrance of lemongrass.
