On-campus dining options vary by time of year and by category of Stanford affiliation. There are more options and longer operating hours during the academic year, and employees and students have more payment options and available discounts than temporary Stanford visitors.
Stanford Dining operates dining halls within the undergraduate residence halls. Anyone can purchase meals at the dining halls. Please see the Stanford Dining  web site for detailed information, including meal prices and dining hall hours and locations.
In addition to the dining halls, there are several wonderful Stanford Hospitality & Auxiliaries retail dining locations  on campus. Stanford’s Visitor Information web site also maintains a list of retail dining operations on campus .
