I think most people are missing why Millennials eat out. As someone close up to a bunch of them, I offer that it's not about convenience a lot of the time, but about the gradual expansion of "family" to mean the chosen family of friends. The conversation and sharing is as important as the food, which often isn't fast food or expensive food. My kid's been eating dinner out with friends since Grade 11. She also had kids over lots of times but in the modern world, it isn't always possible to accommodate everyone around the "family" dining room table. Increasingly, we are living in small spaces that don't have those either. Lots of things going on here. Let's not dump on Millennials for eating together.
