Clarke's was exactly as billed - nothing fancy, but outstanding hamburgers and a pleasant, casual atmosphere. We were looking for a simple, quick dinner out and Clarke's met our goal. There are plenty of other choices on the menu, but burgers grilled over a charcoal fire are the centerpiece. They have plenty of "fixins" for people who like to pile on, and fresh salads as well. The seating area is very casual but clean, and would be great for a family with children or a group of friends. There is also plenty of outdoor seating available. We will definitely make this a regular stop next time we come to Mountain View.
