This is a bustling airport so be prepared to move quickly when necessary. Baggage claim was easy peasy, check-in on return was a breeze and security flew by also.
The gate that I left from was stacked with people so find a nice spot to sit until pre-boarding and don't move otherwise someone will steal your seat and you'll be standing or sitting at a gate further away.
The restaurants in the area of C3 looked inviting and they had some tasty offerings, above and beyond what I'm used to seeing in Detroit anyway. Sandwiches, pizzas and taquitos if memory serves me....just a few nice options while you're waiting.
