This is where the Bride and Groom will be spending their wedding weekend. It's walking distance from the restaurant and from Old Town Pasadena.
Flight
Los Angeles has two major airports, but LAX is definitely the easiest (and cheapest) for domestic flights. LAX is about an hour to and hour-and-a-half from Pasadena, depending on traffic and arrival time.
Flight
Burbank airport is definitely more convenient and is only a 30 minute drive to Pasadena, but it may be difficult to get direct flights, especially for guests coming in from the east coast.
