Most of the restaurants on this itinerary are located in close proximity to each other in Newport Beach. It's recommended to rent a car for the trip, which can cost around $100-150 per day. Brief taxi or ride-sharing services may also be useful depending on parking availability. Driving time between locations should be no more than 15-20 minutes.
If you have more time, consider visiting other nearby areas like Laguna Beach or Balboa Island for their food scenes. Alternatively, if you have less time, select one meal option from the itinerary to fit your availability. Be sure to check online for reservations and current restaurant hours beforehand. Lastly, don't forget to bring comfortable shoes since some locations require walking on uneven surfaces or hills.
