re: What are five "can't miss" things when traveling to Baton Rouge?

Some things not mentioned for those that aren't here centered solely on Gameday (some visit BR on other days):

Spend a night at Myrtles Plantation, and visit Magnolia cafe in St. Francisville, plus the shopping district.

For antiquers and artsy people: go visit 1857 and all the little shops there.

History buffs: visit Port Hudson battleground.

Walk the Lakes and grab a coffee at Garden District Coffee( they roast their own beans everyday)

Grab Sunday Brunch at Duvics( possibly best brunch in town).

Eat at Chealseas. Do it. Maybe catch a show as well.

Grab a drink at Radio Bar and play a game of Ping Pong.

Go to the LSU creamery and get some ice cream.

Take the Tin Roof tour.

Check out the revitalized North Gate area( two new bars are to open just before semester starts).
