When referring to them by their common name, you must uppercase. It's surprising to find "student cafeteria" on a building because that's the building's title, and as such, the words should start with uppercase letters. It is the name of a certain building (Vancouver City Hall). However, when discussing the facility itself, you should use lowercase because it is not a proper noun. The student cafeteria at Vancouver City Hall is a specific location within the building where students can get food and drinks. Lowercase lettering is used to identify many different locations within buildings. For example, the employee cafeteria is usually located on the first floor of the building while the visitor's entrance is on the second floor. Capitalization is also important when referring to organizations or businesses that operate canteens or cafés. The Student Union Building at the University of British Columbia is known as UBCSU in short, and its cafeteria is called SUB. Similarly, the Bay Cafe located near Stanley Park is known as the Bay Cafe in short, and its menu offers items such as sandwiches, salads, and desserts. These are just some examples; there are many more cases where capitalization is necessary in describing public facilities or private businesses that provide meals. Hopefully, this guide has helped you understand how to properly capitalize names of public institutions and private businesses.
