My DD went with friends to PCB a couple of weeks ago and had them check on the Mariner. I described the exact location to them (the adults) and they reported that they "didn't see it" They reported there's a parking lot to the left of the new hotel that was built/remodeled. They didn't see asign or the building. So either they weren't looking in the right place or it's no longer there.
I'm planning another trip for October for the Seafood, Wine and Music Festival and I'm gonna call around and see if I can find anything out. If I don, I'll post.
I hope it's not gone. I looove the Mariner, we ate there every single year. Really nice people, too. We tried Captn Jacks last trip and it was OK. I wasn't impressed with the food. But DH wanted to gorge on crablegs. So I ate 2 plates, DD each had 2 and we sat in the freezing AC for 1 1/2 while DH pigged out on crab legs. He got his $$$'s worth..I stopped counting plates at 12
