McDonald's is McDonald's. You know what to expect when you go in. The food is good, reasonably priced and fast. Check the nutrition info if you want to eat a more healthy meal.
I've dined at Wendy's a few times in my 54 years on this planet. The food has never disappointed me. It's near the high school, so lunch time can be quite busy.
I love Subway. They have all sorts of healthy selections to choose from and that makes a big difference when your other choices are mostly deep-fried.
