I live in San Diego and visit Disneyland frequently-- the food there is crazy expensive, so I eat at various places along the highway.
I stumbled upon 2 For 1 late at night and desperate to find food before the 20-mile dead zone of highway encompassing San Onofre and Camp Pendleton. The staff was extremely pleasant and friendly, and I snagged a generously-sized pizza, order of breadsticks, and 2-liter soda for somewhere in the neighborhood of $9.
At this price, I thought I'd be getting something of poor quality but I was pleasantly surprised-- the pizza and breadsticks were flavorful and filling. Perfect for a late dinner, and I fully intend to visit again-- next time I pass through San Clemente.
