From Ventura to Hillsboro Dr. is about a mile south. At A1A & Hillsboro you'll find 3 nice restaurants, JB on the Beach, 123 Ranch, Luna Rosa, you'll also find 2 casual restaurants, Flannigan's and Whales Rib. There is some shopping there but not much, beach store with t shirts and such, convience store like a 7/11 type and a couple of other small shops. Any other shopping like groceries or the mall you really need to drive to.
Ventura is a nice place to stay, enjoy your trip!
