Diamond's Edge Restaurant & Marina Reviews

My partner Andrew and I were married at Diamond’s Edge Restaurant & Marina in September of 2023 on what was one of the best days of our lives. Planning for the event began roughly a year earlier when, after returning to Maine to raise a family, we sought a wedding venue that would highlight the treasured coastal natural beauty while still being close to Portland. We came to find out that Diamond’s Edge Restaurant was the diamond in the rough we sought.

Stepping off a classic Casco Bay Ferry onto the dock, you are immediately transported away from the hustle and bustle of everyday life into an iconic scene of Coastal Maine tranquility (and away from cell service!) No cars are allowed on the island, resulting in a truly relaxed island experience. History buffs also have the chance to explore historic Fort McKinley - a highlight we didn’t appreciate until after the fact. Whether your guests stay at the Inn at Diamond Cove, a vacation rental, or visit for the day, it will surely be an experience they won’t forget.

The venue itself was remarkable on every front. The scene of a tent reflecting on the ice pond is stunning, only exceeded by the view our guests were treated to with the cove in the background during the ceremony The culinary experience was exceptional, and it was an absolute treat getting to choose from their diverse and rich options for appetizers, entrées, and drinks. But what sealed the deal was the amazing staff of the restaurant, marina, and inn. Their willingness to go the extra mile, find solutions, and focus on the details was so assuring, only exceeded by their commitment to Andrew & I savoring every moment on our wedding day. Thank you, Colleen, Erik, Trent, Crystal, and your whole team!

I got married in September on Diamond Cove and it was an amazing day! Colleen the coordinator was helpful day of as well as the months leading up to it. The location is absolutely spectacular, truly couldn't be more beautiful. The food was delicious, too! Highly recommend.

We had an amazing wedding experience and it would not have been possible without our amazing venue! The staff goes above and beyond as soon as you book with them, and our family is still raving about how kind and accommodating they were during our wedding weekend. It was so convenient to have our ceremony space and reception area next to each other, and our getting ready rooms just a short golf cart ride away. We hosted our rehearsal dinner with them, and the food was top notch for that and for our wedding reception. Having a built in day-of coordinator through the venue was so great, and kept everything running smoothly with vendor coordination and timeline. Not to mention, the backdrop for pictures cannot be beat with the ocean at your feet. I grew up coming to Great Diamond Island during the summers, and I have a whole new appreciation for it now. The island is absolutely magical. I highly recommend booking with them, you will not regret it.

The team at Diamond's Edge was incredible. Everything was planned with plenty of time and the day-of coordinator was extremely helpful. We were able to have the wedding of our dreams, and the team got us through the three year wait for our big day. The food was incredible, and they were able to be flexible within our package so that we could have what we really wanted. Our guests loved the setting and it was truly picturesque. We can't stop looking at our photos! I was a little worried about the destination being an island, but they are a well-oiled machine and made sure that all of our vendors and guests got there. This included our older guests with limited mobility. Thank you to Colleen, Grace, and the team!

We (two grooms) held a destination wedding at Great Diamond Island. Diamond's Edge provides the tent, tables, chairs, linens, food, alcohol and other things I'm probably forgetting. The day was everything we hoped for and more. It was beyond our expectations. Many of our guests, including my 85 year old mother, said it was the best wedding they've ever attended. If you're looking for a classic Maine setting with delicious food, this should be at the top of your list. The service we received from the management team far exceeded our expectations. You can literally hand over your trust to Jason and know you'll have a perfect day. I'm especially appreciative that they thought of details we never considered. The day was stunning, stress-free, and as memorable as hoped for. We received so many compliments on the setting, quality of food, and organization (we had 178 guests). After considering many options in the Portland area, we feel incredibly fortunate that we chose Diamond Cove. We will have fond memories the rest of our days....

Food was fantastic! Way above average for banquet food! Our special requests were easily accommodated! We had concerns about the logistics of a wedding on an island, but It turned out to be much less of an issue than we thought! Having the Inn on the Island for our wedding party made it even easier!

Diamond's Edge is a GORGEOUS place for an outdoor wedding in Maine. A ceremony under a gazebo on a lawn overlooking the ocean followed by a tented reception with a gorgeous view... it was absolutely perfect. The food is amazing and the people were great. I highly recommend this venue for a perfect New England wedding.
