Just "Topolo" – that’s what people-in-the-know call it. Frontera Grill’s sister restaurant, Topolobampo, shares the front door and bar. But then the sister flaunts her own. If Frontera rocks and claps, Topolo slinks. She is the quiet, sleek, classy sister. And she invites you into an elegant Mexican fantasy world and to dress up a notch for its incomparable, authentic, regional flavors.
