Fans didn't only show up to party, they came by the hundreds and packed in Tom's Watch Party restaurant at L.A. Live across from where the Lakers play.
"We got more fans here than are probably going to be at the stadium for the Rams," said 49ers fan Omar Valdes.
"Gilroy, California! Garlic capital of the world baby! We're coming at you and you know we're gonna get you!" yelled one 49ers fan.
Intensity at this 49ers party was an understatement.
Everyone attending decked out in their favorite 49ers chain, best looking helmet, flashiest Niners jacket, coolest 49ers tattoo, and best looking nails.
"This is my deep red, with the gold, kind of glitter. I got to do it all for my boys," said 49ers fan Karen Nowack of Sacramento who continued by saying, "Yes I love this, I love this! We had no idea, we came a little earlier but this is insane, this is crazy, this is who we are."

Over at Randy's Donuts on the other side of Los Angeles, Rams fans lined up for fancy donuts.
"Send those Niners back home to the bay!" yelled Rams fan Keri Noonan.
But the crowd at Randy's, not anywhere close in comparison to the number of 49ers fans who partied at L.A. Live Saturday, fans who had responses to those in blue.
"You know what?!?! It doesn't matter what the Rams fans said! It doesn't matter!" said 49ers fan Fabian Rivera of South San Francisco.

"Well that was your first problem, you were believing someone that was on the Rams," said 49ers fan Kirk Herzog.
And if you think there was a lot of scarlet red Saturday, many here say there will be a whole lot more come Sunday.
"Somebody told me it's not going to be a sea of red, it's going to be a tsunami," explained ABC7 News reporter J.R. Stone to 49ers fan Amanda Rodriguez. Her reply was simply, "I agree, I agree, the sea is here and the tsunami will be there tomorrow!"
