re: Any tips for a first time visitor to a Saints game?

I vote against Champion’s Square too. It’s set up like one of those sunbathing reflective devices women hold at their neck to get a tan on their face. Hot as hell even on cool days, overpriced food and beer. You’ll be exposed to that soon enough in the dome.

Mass and FQ bar hopping sounds good. You may look into doing a brunch with unlimited bloodies or mimosas.

As for tops, if you’re not looking for a jersey there’s a t-shirt shop on Royal St. called Dirty Coast. They have a cool line of Saints related t’s. You can look at their stuff online. Just google them.
Have a great time.
