Every year around the end of August the city of Orange hosts the Orange International Street Fair where thousands of people walk from booth to booth eating native foods from Sweden, Germany, Japan, and Mexico as well basically every country you could imagine. Last year was my first year attending and I can't wait to go back this year.
The event takes up essentially all of downtown Orange and while it is convenient for attendees to try each booth out it makes the place a nightmare for anyone who has never decided to drive through Los Angeles.
Unlike most of Los Angeles parking is easily available in the surrounding neighborhood and you never have to drive farther than four or five blocks before you find parking. If you decide you don't like walking they have parking lots that range from $10-$20 for an all day pass.
WHY YOU SHOULD GO HERE
In a word: street food. It's not all good but when it is, it's really good. The food during the event is a hit or miss. There are plenty of pubs to go in and out of and with no shortage of bavarian hotdogs and kabobs you could easily spend two or three hours here walking around and eating. The food here ranges from mediocre to fantastic but like most people I come here to see the spectacle and it's always something fun to do locally on a weekend.
