Sometimes it seems like Scottsdale is home to more sushi joints than good old-fashioned Mexican restaurants, but if you know where to look, there is definitely South of the Border grub to be found. In the case of La Fonda del Sol, it's at the north end of a quirky retail complex on the southeast corner of Scottsdale and Shea, home to a diverse collection of restaurants that encircle an expansive parking lot. Although some of its neighbors might be upscale dinner destinations, La Fonda del Sol is unquestionably casual, more charming for its friendly service than for its atmosphere. But hey, we're not here to gawk at the décor, anyway. What gets us in the door is cheap, satisfying fare like green corn tamales, luscious carnitas tacos, machaca-stuffed chimichangas, and killer combination plates. Come lunchtime, it's even easier on the wallet, with a belly-busting all-you-can-eat buffet for under seven bucks. Nope, you can't find a deal like that at any sushi place, period.
