Re: Hamburgers on the way to the Oval Nationals.
In-n-Out is OK at best. Five Guys will kick their ass all day long. Farmer Boys is only about a mile from the track and serves up a decent burger if you didn't have time to stop anywhere else. It's a lot cheaper than eating at the track.
But, if you're travelling through San Diego, the single greatest hamburger ever devised is found at Hodad's in Ocean Beach. Just head down Newport Avenue and look for the hungry people standing in line. Absolutely worth the drive and the wait. A behemoth of a burger that requires 5 napkins, minimum.
Honorable mention goes to Slater's 50/50, also in San Diego. Close to the airport, their burgers are made of 50% beef, 50% bacon. Expect to wait here also.
