I live in a small (3500) Midwest town, and fast food is a McDs, a Subway and a Culvers. I very rarely frequent any of them ... fast food is what I do when I have to go to Florida to do family obligations, and after 3 days in the car, eating fast food, awhile there, then three days back, I never want any of it again.
That said, the last Florida trip made me discover that Dunkin Donuts (I think that's the chain) has pretty damned good croissants. This is the bane of my existence. I was introduced to truly great croissants at, of all places, the Pentagon bakery. I mean that literally, the Pentagon had a great bakery and their Friday morning special was croissants and they were to die for. I haven't had a good one since, but these are better than any others I've bought.
To me a burger's a burger. Yes, there are some that are really good, and some that are really bad. But .... it's still a burger.
A number of years ago (I'd say 3 or 4), towards the end of menopause, my sense of smell went off. I've recovered most of it, but the smell of rancid grease puts me off my food. Others might not even notice it. But when I had to eat fast food for an extended period of time .... I lost 10 lbs.
Next time we head to Florida (it's all a matter of time, my parents are 78 and 82 years old and both in poor health), I hopefully will have the time to hit the grocery store and fill a cooler with makings for good food. Of course, any time I do that, the weather turns to h in a handbasket, and all we want to is find a place to duck inside.
