If cod tongues are available, I believe Seaside REstaurant inTrout River serves them. As for Jiggs dinner - last year the Jackladder on Route 430 just east of the park served it on Sundays. Also I think maybe Earle's in Rocky Harbour served it on Sundays. Not sure what they are doing this year. When you are in the park check local churches or fire companies for jigs dinners. Many times they are prepared as a fund raiser.
