I have a flight out of LAX around 11AM, but I'm going to be getting into the area around 6AM or so. Will any good breakfast restaurants be open along Venice Beach before 9:30AM or would I be better off just going to LAX and eating/hanging around there?
You'll find no shortage of Breakfast locations along Venice beach, all open from at least 8am, many 7am or earlier.
Although I've never been there for breakfast, it's hard to go past Figtree's Cafe, if only for the view and because they do a half-price happy-hour from 8am to 9am.
Other than food venues you won't find much else open until around 10am.
