HI, we found it this trip in March / April

Leaving Simpson Bay, before the roundabout, there is a large Casino on your left - Princess - , just past, there is a road to the left - Waterfront Rd - which ends up following the east end of the lagoon shore. That road meets Wellington, keep left, follow at least half way - Lagoonies is on your left. A little hard to find, it's behind a Yacht rigging company - FKG Rigging - maybe a red building?. Drive in,parking on the side
Liked the vibe, food and drinks
