Are there signs to direct you to these parking area

Last time i was there no tvs just outside dining

Yes, outside on the deck

No. It's more difficult to find parking than get a table.

No you don't unless your party is more than what they serve over 6 or 8 at a table I believe. Going to be more convenient to call in if you have a large party indulging in delicious Seafood and mixed drinks.
