    I toured and had brunch at Diamond on Seneca over the summer, and I was so excited to see this new venue is now opened! There is a wide and spacious terrace with gorgeous views of Seneca Lake, great for cocktail hours or even a ceremony. The food and cocktails are outstanding with lots of variety. The service was top notch, no surprise as this owner also owns New Park a very popular and beautiful venue spot closer to Ithaca. However, one other standout feature is the main dining room- complete with a floor to ceiling fireplace and huge windows with that beautiful lake view. This roomy dining room has so many possibilities: a winter wedding with snow, a fall wedding without worries of the weather - and still views of the lake and foliage, alternative options for Spring where it can be muddy or July where it's so hot. All of those concerns go away! This new space I am sure will book fast.

    Diamond on Seneca was the perfect venue for our wedding. The staff was incredibly welcoming and made us feel like family from the moment we walked in. The views from the venue were absolutely stunning, with beautiful sights in every direction. They went above and beyond to ensure our special day was everything we dreamed of and more. We are so grateful to the Diamond on Seneca team for helping to make our wedding day truly unforgettable.
