I can't remember the last time a city has actually smelled bad to me. I always seem to smell the food vendors when I am walking around. Pretzels and hot dogs and roasted peanuts and stuff like that.
Probably the best food smell I have known in a big city was in Boston, in the area around Fenway Park.
Although Camden Yards has great food as well, with the requisite smells.
'Tis true, you know.
May I have this "How you doin'", my dear?
