I like Taco Bell -- I always get the chicken quesadillas and I love those cinnamon twist things they have.
McDonald's is the closest fast food place to my house so when I'm craving bad food, or needing something quick, that's typically where I go. I looovee their chicken nuggets so I just will get myself a 6 piece kids Happy Meal with one of their Strawberry Banana smoothies. <3
When I'm craving Mexican though, I go for Chipotle. Not a drive-through but super fast service, AMAZING food, and it's actually good FOR you.
