I dined here on Christmas Eve while vacationing in Ojai (I didn't stay at the Inn). I arrived early and was escorted to the lovely Marvilla bar and expertly handed off into the care of an attentive bartender where I enjoyed a glass a wine he recommended. That was the beginning of the spectacular service that never waivered during my entire meal. I often travel alone and many fine restaurants like to stick solo female diners in a corner and forget about them, or hurry them through their meal. I don't care how good the food, I will slap down a restaurant for such demeaning service. It was the exact opposite at the Oak Grill. I was fawned over like a favorite visiting auntie by an army of waiters who addressed me by name each time they approached.
For Christmas Eve the Oak Grill offered a 3-course Christmas Dinner with a choice of two soups, entrées and desserts - but you could also order from a selection of their regular items. I went with the prix fixe menu. My one complaint is that they only offered prime rib or baked ham for the entrée and should have offered a fish choice as well. I chose lobster bisque, prime rib and black forest cake for my Christmas meal.
The lobster bisque was not the traditional thick cream based chowder with chunks of lobster. Once this New England born gal got past that, I enjoyed it immensely. It was thin and strained with nary a shred of lobster but the lobster flavor came through loud and clear, along with truffle. The prime rib came with a twice baked potato that was very dry and plain and perfectly grilled asparagus. Although I ordered the meat medium rare, it was more medium well and a bit on the dry side. It was an ordinary prime rib you can get most anywhere. Dessert though was da bomb! A deconstructed black forest cake with a dark chocolate cookie/crust then a layer of some sort if creamy custard, then a layer of cherries soaked in brandy followed by a dome of more custard dusted with bittersweet cocoa. I could have eaten a bowl of the cherries alone. The portions on all courses were generous and I brought half the meat home.
