McDonald’s has been promoting their new McCafé Frappés with a series of events throughout Southern California.

First up was Santa Ana last Thursday (May 6) , followed by the event in Riverside last night (May 11), which Dine 909 happened to spot on Twitter and stopped by.

For this final event, we’ve got a little advance warning.

It’lll be from 6 to 8 p.m. tomorrow (May 13) at the McDonald’s at 27774 Base Line.

Music will be provided by Power 106′s Flava Unit, and you’ll be able to sample both the mocha and caramel McCaf Frapps for free!

Last night in Riverside, there was also a steady stream of free food provided — McNuggets, fries and Snack Size Fruit and Walnut salads were handed out in Riverside.

They even had prize giveaways, including a $50 McDonald’s gift card.

The events are being promoted via Twitter, so for updates and more information, follow @McDonalds_SoCal on Twitter.

Who knows…you may see us there.
