So, What's Your Favorite Burger Chain Place?

I have been on a lifelong quest to try the best burger in every town I go to. I'm sure @krazykuda can attest to Millers, the Redcoat, the Sidetrack and other Detroit favorites. The Hunka Hunka Burning Burger at Marlowes in Memphis was a great burger too. Funny that Nella has never had a hamburger in her life, and wants nothing to do with trying one, or any kind of sandwich for that matter!!
