It is about half way between Los Angeles and San Diego and is the best American embodiment of planned suburbia. Six-lane wide avenues and endless subdivisions of single-family houses surrounding pockets of strip malls are the norm.
The proper name in Spanish should be Misión Vieja, as 'mission' is a feminine noun. The masculine gender of "viejo" is a vestige from the original name of the area, "Rancho Mission Viejo" ; "viejo" modified "rancho", a masculine noun. In light of the history of the area, the masculine adjective was preserved. The "Mission" of "Mission Viejo" is Mission San Juan Capistrano ; Mission Viejo was a community of San Juan Capistrano until it became an independent city in 1988.

Most Mission Viejans shy away from their local restaurants for all but casual dining, and prefer nicer restaurants in adjacent communities. However, it has a few gems:
Thainakorn Restaurant, 25482 Marguerite Pkwy.  "Authentic" Thai food restaurant where Thai folks go to eat. The little sister of the real Thainakorn (in Buena Park) but great food at the price of under-par customer service. For the uninitiated, chicken satay and pad thai are safe bets.
In-N-Out Burger, 28782 Camino Capistrano. Californian readers will agree that this is an American institution. Fresh, cheap food in a clean restaurant. The menu is limited, but search online for their "secret code" for access to unlisted items and combinations.
Hatam 2, 24000 Alicia Parkway. Good authentic Persian food.
PF Chang's China Bistro, in the Shops at Mission Viejo; Authentic Chinese cuisine.
The Cafe at Nordstroms, also in the Shops at Mission Viejo; excellent pastries, lattes and espressos, far superior to the Starbuck's variety (prices are reasonable).
Shin Sushi, 26002 Marguerite. Fresh authentic sushi prepared by a master.
Peppinos, 27782 Vista del Lago #26. A family owned Italian restaurant with sweeping view of Lake Mission Viejo in Plaza del Lago.
Tortilla Flats, 27792 Vista del Lago. A delicious Mexican restaurant located in Plaza del Lago with sweeping views. The beautiful Spanish building is popular for weddings.
Yama Sushi, 27782 Vista del Lago. One of Mission Viejo's best Japanese restaurants with a unique menu. Located in Plaza del Lago with lake views as well.
The local favorite is Patsies Irish Pub on the Corner of Los Alisos and Jeronimo. It is a typical American/Irish bar and is fun place with great drinks and karaoke.
