The Glass Onion is a classy 'joint', with simple but refined ambience and decor. It is not inexpensive, but for the most part, it's nice to have a dining experience that is not the run-of-the-mill Cape Cod large family eateries. The service was very attentive, with our server very knowledgeable about the menu as well as the Falmouth area. My wife and I shared the beet salad, ample for two, and then she had the Halibut special ($36) while I had the "7X Culotte", which may sound like a fashion statement but is actually a steak descriptor from Colorado ($35). Both dishes were quite tasty, prepared well and nice sized portions. The wine by the glass is reasonably priced ($9), while the coffee is not ($4), but that's just my pet peeve. All in all, it was a delightful dining experience (despite the table of very loud people nearby) and I recommend it if you are looking for a place that is special.
