The taco is a funny beast. Simple versus fancy. Food truck cheap versus schmi-schmi expensive. Naked versus overdressed. So many choices, so little time. The fish taco at this suburban Chicago walk-in joint is perfect. Grilled tilapia, onions, cilantro and home-made chipotle sauce. Two warmed delicious corn tortillas and an excellent hot sauce chaser. Supremely satisfying on a winter’s day.
