This place is located in the MTV Building in Santa Monica and is the cafeteria. It's decorated pretty nicely and has decent food at decent prices. There are stylish booths and a nice outdoor area with tables.
The food is pretty standard American food. Salad bar, grill with hamburgers and chicken, soda fountain, junk food. It's priced pretty reasonably, so lunch is typically less than $7.
It's cafeteria style, so you grab a tray and start loading up. Pay at the register and then try to grab a table. For the members of the Lonely Hearts Club Band, they are even nice enough to provide newspapers and magazines if you just want to read while you eat.
