The latest trend in Bangkok seems to be dog fighting. Not the cruel sport pitting canine against canine, mind you, but the culinary sport pitting hot dog vendor against hot dog vendor. Thankfully, the winner of this contest is the frankfurter-hungry consumer. Two hot dog companies have opened recently: Superbdog and Corn Dog Dude. Their promise is true American style hot dogs. Accompanied by my Floridian friend John, we set out on a recent evening armed with antacid tablets, ready to try both companies’ offerings.
