Duarte's (click here for address and info)
This Pescadero restaurant just off the coast is insanely old (since 1894, yo!), somehow serves 13,000 people per month (despite being located in PESCADERO), has a James Beard honorary award for being an "American Classic", and they have the best Olallieberry pies in all of California (shut up, good SoCal pie places).
Ikeda's (click here for address and info)
This on-the-way-to-Tahoe roadside diner has a sign out front that reads, "Tasty Burgers / Fresh Fruit". And don't get us wrong, both of those are great (in particular, the Ultimate Big Burger, which they have to serve on a French roll because it's so big), but the reason it makes this list is Ikeda's salsa bar. Located a foot inside the attached market, they've got a whole section dedicated to tasting salsas, with chips provided so you can get the real-deal experience.

Grant Marek is a Senior Editor at Thrillist and is pretty sure if you don't agree with any of the picks on this list, they were probably Joe's. Agree with him completely on Twitter.
