However, I was able to find information about the Fairfield Inn & Suites by Marriott Oxford, but not specifically about a "restaurant" with that name. It appears to be a hotel or lodging establishment.
If you're looking for information on a restaurant associated with the Marriott chain at this location, here's what I found:
The Fairfield Inn & Suites by Marriott Oxford offers a complimentary hot breakfast buffet each morning, featuring items such as scrambled eggs, sausage, pancakes, and pastries. They also have an indoor pool and fitness center.
Their rooms feature free Wi-Fi, flat-screen TVs, and comfortable beds with crisp linens. Some rooms even offer separate living areas for added convenience.
Guests can enjoy a 24-hour market on site for late-night snacks or other essentials.
The hotel is located in the heart of Oxford, within walking distance to several shops and restaurants.
