To assume that Refresqueria Rio Verde is simply a refresqueria would be incorrect.

Although the sides of its white-and-red truck are painted with the colors and flavors of the various raspas it sells, you may miss the comparatively less emphatic "tacos" and "tortas" that look like afterthoughts. You'll need to get up close and personal to find that menu: smaller, partially hidden behind the plastic trays full of condiments for truck's elotes and freshly sliced fruit -- both snacks waiting to be sprinkled with rust-colored chile en polvo for a spicy kick.
On that small menu, you'll find that aside from just snacks, Refresqueria Rio Verde also serves a full menu of tacos. I sort of hate that I'm telling anyone this, but they're one of the best-kept secrets in town.
