I hadn't been to The Glass Onion in several years so I decided to try it again. I had gone to a new restaurant the last couple of visits to Falmouth but I like the atmosphere of this restaurant better. If you want a relaxing nice evening this will do the trick. If you have to wait for a seat... More

Excellent service and good food but not an exceptional meal. Our waitress was very attentive and she made excellent wine recommendations. The duck was perfectly done and delicious but with only 3 small medallions on the plate it felt over priced at almost $30. The lobster and shrimp risotto was visually stunning but I found my lobster tail to be... More

Wonderful restaurant! Food and service was excellent! I ordered the butter poached shrimp and lobster on top of risotto. It was divine! Perfectly cooked and a good sized portion. I got the tres leeches for dessert and it was perfect! They top it with strawberries and cinnamon whipped cream. My colleagues got the house made ice cream and a chocolate... More

This place got a tremendous write up in a travel book we got. Nice outside, lots of people, figured we'd go in and have a nice seafood dinner. Guess what? It's a cafeteria style restaurant where you stand in line and place your order and then get it and take it to your table! Not my idea of a nice... More

This is one of the best restaurants we have been to. Great menu, wine list, service, and ambiance. One down side noted is that it is loud due to there being hard surfaces throughout with no sound dampening surfaces. The sauces are rich and well done. Service very attentive and knowledgeable. Great wine list. Crowd tended to be older. Not... More

This was our first dining experience at Glass Onion and what a delight! We were welcomed upon walking in the door and the smiles and excellent service continued throughout. Our waiter, Chris, was supported by a wonderful staff of servers. We feasted on a pear salad followed by filet mignon, cooked to perfection, and the sea bass special. The food... More

Excellent dining experience! Our evening at The Glass Onion began with wine and unique cocktails. The cucumber vodka tonics were refreshing and delicious. The salad special included a roasted pistachio and cherry enhanced bib lettuce salad that was amazing. The entree menu was fascinating to read because it was written so eloquently with such details! We dined on beef barbacoa,... More

I was vacationing in Falmouth and kept hearing about the Glass Onion. What a fabulous restaurant....not typical of Cape Cod. I enjoyed one of the most delightful dinners, an amazing Cambodian/Vietnamese Pork belly that was so fresh in it's flavors and such a departure from normal fare.,The monk fish was superb, sauce work brilliant, terrific wine list and just all...
