You do, in fact, realize that the "Southern California" area encompasses thousands of square miles, and takes at the very least 2 hours to drive across?
Now, be more specific with the following:
1. Budget
2. Food Type
3. Ambiance (calm, ocean view, trendy, people-watching, etc.)
4. LOCATION (valley, westside, mid-town, pasadena, south bay, san gabriel, san diego, riverside, inland empire, etc..)
