Our West Lounge hosts up to 45 guests.  This space is ideal for rehearsal dinners, corporate events, and upscale banquet dining. The west lounge is separated from our main dining room and features floor-to-ceiling windows overlooking the Piscataqua River that open up to allow the fresh ocean air to breeze through.  


Our East Lounge can accommodate up to 50 guests. This room is equipped with a high-definition television monitor for presentations, or photo/video display. It is furnished with a combination of high and low-top tables. It uniquely features a waterfront countertop rail which spans the entire length of the room.  Floor-to-ceiling windows open directly over the stunning Piscataqua River allowing for stunning sunset backdrops and an open air atmosphere. 


This includes the main restaurant dining room which has a large circular bar, the west lounge, and the 100 foot outdoor waterfront deck. All together, this option is ideal for large events up to 200 guests.
