Here is a video of the Los Angeles River Center and Garden that was taken from an actual wedding video. The nice thing is that since I do about 6 songs worth of intensive editing with each preferred wedding you get footage like this that lasts for more than 10 seconds. The Los Angeles River Center is a great venue and offers much in the way of feel and ambiance. The two fountains that grace the first courtyard and the main courtyard add constantly throughout the day, especially into the reception when the main one is lit. From rustic gates to wooden doors to plenty of plantlife, the Los Angeles River Center is great for any wedding's ceremony and reception. If you have any issues seeing this video, you can find more in the sample wedding video section. Here is a link to the official website.
Here are some pictures of the Los Angeles River Center and Garden for those that cannot see the video above. However, I'd always recommend seeing the video, since it offers so much more than any picture. One can see the two fountains that center the venue, with the fountain in the foreground being the one in the first courtyard. The third picture shows the venue at night, though each wedding will have unique arrangements and table setups.
