Seattle -- not quite as gay as you thought
From a 2006 NPD press release about which cities are most vs. least desiring of more healthy items on restaurant menus, we see that Seattle scored among the least, along with a bunch of cities that the SWPL crowd would never live in (although they might visit just to have a story to tell about their brush with gritty street life).
Of course, "healthy" items means high-carb garbage with no intrinsic taste, and so therefore has ten pounds of sugar dumped on it -- blueberry muffins, pumpkin spice bagels, etc. Or a bunch of empty carbs with fat heaped on top to provide some actual taste. Unfortunately that won't stop the pasta or rice from spiking your blood sugar and raising your insulin levels, so you'd be healthier to just heap the fat on some more fat, along with protein.
Most restaurants don't do that unless they charge an arm and a leg -- after all, a high-carb meal is for starving peasants -- except for those Brazilian grills that are popping up all over. Perhaps being from a third-world country, they know that you don't fuck around when people plunk down $15 - $30 for dinner. Poor people get enough bread, rice, and sugar at home because it's cheap. When they go out, they want envigorating food like sirloin, chorizo, and quail eggs.
