Mofongos restaurant in North Hollywood was collecting supplies all day Sunday and the owner committed to donating 25 percent of the day's proceeds to help the people of Puerto Rico.
A coalition of groups called Los Angeles for Puerto Rico has also been collecting supplies, including food, water, toiletries and other items.
Puerto Rican actress Roselyn Sanchez also organized an event in Hollywood to help collect supplies.
She said people were donating everything from water filters to clothing to canned food and flashlights.
"We are in a lot of need," said Sanchez, who starred in the show "Without a Trace." "People think yeah we're getting a lot of support, we appreciate it. But this battle is going to continue for a long time."
