Interesting choice to go from the states to Canada ... to have Cajun cuisine but Big Daddy's was within walking distance from the hotel and and since it was past 10:30pm on a weeknight, we weren't too terribly fussed.
I'd say everything was just ok here, including the BBQ pork back ribs, the popcorn shrimp and the raw oysters. The oyster po boy had a strong fishiness to it that didn't appeal to me.
Sitting outside on a summer night was the highlight. Almost perfect weather, low humidity and with a thin jacket that you don't really need but like to carry around.
Service was friendly although a bit slow at times.
