Rancho Capistrano Winery (RCW) boasts the largest winery in Orange County. They are located in the heart of San Juan Capistrano. SJC is a cute little city with boutiques, coffee shops, a small petting zoo for the young ones and the famous Mission San Juan Capistrano. It makes for a great day trip on the train (Metrolink OR Amtrak). Keep an eye on the schedule though, you may find yourself spending the night in San Juan.
South of Nicks
Where to begin with South of Nicks! Being that I am originally from Texas, finding excellent Mexican Food is super difficult (Yes, I know I grew up on TexMex) because I am so darn picky. A friend of mine recently recommended South of Nicks (she is a SoCal native). It did not disappoint.
