@Xochitl – re: Dookie Chase, I just sit at my table and eat other things until I see a new tray of chicken come out, and then descend upon it like the vulture I am! ;^)
I prefer Parkway to Domilise, but – to be honest – I think it’s a Cubs/White Sox thing, or an NY Giants/NY Jets thing: six of one, half a dozen of the other; a matter of personal palate preference. I know people who prefer Domilise; I know people who prefer, like I do, Parkway.
re: Killer Po-boy – whereas Parkway & Domilise are steeped in tradition (i.e.: classic po-boys), Killer is totally non-traditional. (Think, say Galatoire’s and Commander’s versus a Cajun-Creole-Korean-molecular gastronomic fusion – both are wonderful, but totally different.) Killer is definitely worth a visit, but don’t expect to see the same old, same old . . .
And finally, re: Casamento’s . . . Now, in the Quarter, people fall into two camps for oysters: they either prefer Acme, or they prefer Felix’s, as the long lines on opposite sides of the street will attest. (I’m an Acme guy, FWIW.) Casamento’s is a bit similar, in that you either love it or you don’t. To be fair about it, let me say I’ve only been there once. I found it to be good, and I would go back if I were in the neighborhood – but I didn’t think it was worth going out to Magazine St. just for Casamento’s. Let me hasten to add there are certainly loads of people who will make a pilgrimage out to Casamento’s and absolutely love it. YMMV . . .
