An absolutely wonderful experience. A vibe true to definition. They open at 5p sharp. We were welcomed and seated promptly. Our waiter was at our table in the perfect amount of time to bring water and take our drink order. The drinks fun and bright kicked off our dining experience with excitement. Moments later, some beautiful, warm bread with spreadable and well presented butter adorned our table. We ordered the Lobster Pastry appetizer. It was decadent and delicious, not to mention incredibly beautiful. We would have licked the plate if nobody was looking... ;-) Between servings, bus staff quickly and discretely cleared and replaced dirty plates and silver. We felt pampered, as if we were the most important customers in the world. Dinner came and it was everything we had hoped for. The duck, cooked medium rare, with skin, and a cherry sauce, was delicious. The fresh green beans and Yukon gold potatoes, the perfect complements. The striped bass, also, flaky, tender, and wonderful. Perched on top of arugula and a light lemony tomato dressing made the dish really pop. The recommended red and white wines paired perfectly. Then came dessert. This brownie thing from another universe. Leaning into a pool of melted chocolate, topped with whipped cream and mint, a luxurious confection that left quite the impression and is in a sugar coma. We left, mesmerized by our experience and wanting to go back. Hands down one of the best most delicious, elegant, and white glove dining experiences we have had out (and there are a lot). Highly recommended. Don’t hesitate.

We celebrated our 25th wedding anniversary here, and our experience could not have been better. Everything was exquisite, from the drinks we enjoyed before our meal to the meal itself as well as dessert. For the price, it is worth the expertly-prepared food, which my wife appreciated as someone with significant food sensitivities. We will definitely be back!

On our 2nd night in Falmouth, we decided to treat ourselves after a full day on the Vineyard. The Glass Onion has been a local staple based on the reviews, so we decided to give this place a try. The interior is intimate and perfect for special occasions and family dinners. Warm tone colors and classic decor the place is cozy. The service was superb, friendly, and attentive, and thankfully, they were able to provide us with recommendations. For drinks we shared a bottle of savignon blanc and their crab cakes. For food they've got a great selection of seafood and seasonal dishes.

A high-end restaurant with a lovely, non pretentious atmosphere. The dining room has this row of giant multi-paned windows that look across the street at a similar old building, which was quite a lovely view with the snow flying on this early evening in February. Their wine list is well thought out with quality and high-end selections at fair prices. The cocktail list is well rounded. I know they have beer, but I can not attest to the options. The food is outstanding, from start to finish. Everything is prepared by a master chef and served to you by an impeccable waitstaff. In a town with a lot of great dining options, this establishment stands out.

Went to celebrate our wedding anniversary and everything was great! The service was great and the food was excellent. The duck was melt in your mouth delicious and the bread they bring to the table accompanied it well. My husband got the seafood risotto. Both the seafood and the risotto were perfectly cooked. We will be back again.

My family and I have dined at Glass Onion numerous times over the years. Not only is this one of the best restaurants in Cape Cod, hands down, it is also one of the best restaurants I’ve ever dined at in my life. The milieu is calm, lovely, and clean. The furnishings are beautiful and thoughtful and it’s certainly a, “fine dining vibe.” The owners are the sweetest and kindest people. They are extremely welcoming, accommodating and always ensure every guest has an incredible experience. I have never eaten anything at Glass Onion that I didn’t love. The salad is so fresh and always made with local ingredients, soups are so flavorful and all of their dishes are carefully curated and executed. We love their cocktail and wine lists too - excellent selections. Highly recommend if you’re in the area!!

Hubby and I went away to the cape for our 10 year anniversary and picked this restaurant as a special night out. We arrived a little early but they seated us right away in the front glass window which was so cool. It was the old glass so when you looked out it was wavy, loved it. We shared a special salad with apples and cave aged cheddar which was delicious! Hubby ordered the sous vous Fillet and I ordered the lobster and shrimp risotto. We both loved our meals. They brought us out house made mint ice cream and to celebrate our anniversary at no charge and hubby said it was incredible! We really enjoyed our dinner here!

Wow! What a wonderful restaurant! Warm, kind people running a restaurant in a light, cosy space. But it’s the food that really sets it apart. So many good choices on the menu, and they were all really wonderful. And remarkably reasonable for such a good place.
