Carl's Jr. continues its eternal variations upon the cheeseburger with the guacamole bacon burger. One of their more successful efforts (I still recall my disappointment with the brilliant-in-concept Teriyaki burger and I continue to vacillate on the matter of the Western Bacon Burger.), it has appeared on the menu before. Now, however, it's being offered in single, double and six-dollar variations, with the size reflected in the price.
I went for the latter (Hey, if you're gonna indluge in the drive-thru, indulge in the drive-thru). and found it to be a darn sight better than the average fast food burger. The patty was thick and juicy, the guacamole was pleasantly spicy and the bacon was actually of a quality and amount to enhance the burger, rather than detract from it, like most fast-food bacon-on-burgers.
The guacamole bacon burger was named the official burger of last month's 2008 California Avocado Festival and it's a pretty solid choice. It also makes me consider what other high-end flavors I'd like to see on my low-end burgers. The grilled pineapple on the aforementioned Teriyaki burger raised my hopes, the the execution was distressingly bland. Mushroom Swiss burgers have been tried with varying degress of success, although the chili burgers are usually not terribly enticing. Toppings like brie, caramaleized red onions, roasted tomatoes or any lettuce beyond iceberg is probably out of range. Still, it'll give you something to mull over next time you're waiting at the window for your extra ketchup.
