Yeah, I think he might. I think most people on here would agree I'm about as elitist as it gets, but for me good taste does
not mean burgers with a lot of weird, innovative sh**t on them. When it comes to food, as in most things traditional is best.
Thailand is full of the most horribly annoying foreigners who go around asking for every dish to be modified in some awful, innovative way. I hate these people. The dish is always best as it has been served for generations! I'm constantly having to stress to Thai restauranteurs here that I want the food 'tamadah' or 'regular', 'sai prik' (put peppers), etc. I want it precisely as Thai people have eaten it for ages, not how some asshole with money thinks he wants.
I'm not saying I would never try a weird-burger, but if I were the president, and could traipse out into the public to get a burger rarely, I would order the simple, traditional burger similar to what Obama ordered. And yes, I most definitely would include mustard on the burger and not ketchup.
I personally find Obama to be mostly a man of good taste, both in his culinary and sartorial choices.
