I didn't get to 5 guys until I moved out west. I love it though - the concept is great and the food is excellent.
@Jordi_Mor I don't eat fast food every day (in fact I rarely eat it - lunch today was a bunch of raw spinach, an avocado, red and orange peppers, carrots, and mushrooms) but man I love it when I can justify it.
Also, I think "fast food" can be widely interpreted around the world ( and even in the states). For example, I had sushi on Monday that was pretty fast, and we have new ramen and pho places in town that I think qulify as "fast" without being so unhealthy.
