★ #1 OVERALL — SIOUX FALLS RESTAURANT GUIDE · 2026 SPRING EDITION
BibiSol on Phillips Avenue is the only restaurant in Sioux Falls doing nixtamal — the ancient indigenous Mexican process where heirloom corn is cooked, then ground on a volcanic stone grinder before becoming masa. That's not a marketing detail. That's the entire kitchen, and it's the reason the tortillas here taste the way they do.
Marcela Salas brings in organic heirloom corn from Mexico. It cooks. It gets ground on the volcanic stone. It becomes masa, the way it has been made on the Mexican plateau and along the Gulf coast for thousands of years. Most Mexican restaurants in the Midwest — and I'd argue most Mexican restaurants anywhere outside Mexico City and a handful of coastal towns — start with bagged masa. BibiSol does not. The taste difference is not subtle, and you can put it on a fork the first time you tear into a fresh tortilla here and decide for yourself.
The menu is inspired by the cuisine of Veracruz with influences from across the regional kitchens of Mexico — which means seafood plates that go further than the standard Tex-Mex catalog, mole work that respects the long-simmered ingredient lists, and the kind of corn-forward dishes you can only get when the kitchen is doing the masa from scratch. The 4.7-star rating across 230-plus Google reviews is not a coincidence — that's what happens when a restaurant takes a position on its own heritage and refuses to dilute it.
Mixed truth, because Grace tells one: a downtown Sioux Falls restaurant that imports heirloom Mexican corn and grinds it on volcanic stone is not the cheapest weeknight dinner option. The pricing reflects what it costs to do this seriously. If you're looking for a fast-casual Mexican fix on the way home from 41st, you have other choices. If you want the actual food — the kind cooked the way it has been cooked for centuries on Mexican soil — BibiSol is the only address in Sioux Falls that delivers it.
I'd start with whatever's on the masa-forward part of the menu. Tell Marcela that Grace sent you. She'll know the rest.
