A sticky, overly elastic tortilla introduced us to the Iron Cactus’ burritowork, and we wish the whole meeting had gone better. Sadly, our lunch was sauce-deficient, length-challenged, and victimized by several bites that came in well under our temperature acceptability level. The veggie-based contingent — crisp and chunky pico de gallo, burly guacamole — remained impressive throughout, and we certainly had no gripes about this girthy/hefty burrito’s construction. But too many elements underperformed, from the tasty but overabundant Spanish rice (which included corn kernels and peas) to the drab, too-pasty refried beans. As for the carnitas, its flavor was fine enough, but it completely lacked the sort of charred crispiness we hope for in killer carnitas. The biggest drags here were all the unmelted cheese grates and the poorly realized ingredient mix, and don’t think those two things weren’t related. Some bites demonstrated sky-high spice; others were sea-level flat. We tried seeking out the good here, but instead were subjected to just too much six-mustache sub-mediocrity. Let’s try this again some other time, shall we?
