Mother's Market is another LC resourse. THere is one in Costa Mesa on 17th and one in Huntington Beach on Beach Blvd. Trader Joes has LC tortillas.
There is a restaurant called Pancho's in Orange on Glassell. Very affordable. They have this Shrimp Ranchero Omelette (sp) that is served with a salad...just tell em to hold the beans or rice. It is very good. Also their Fajitas are great. Just in case you were craving Mexican food.
