What to know
When Tonas opened on South Grand, it planted a flag for cocktails-first Mexican dining in St. Louis. The owner set out to celebrate authentic Mexican flavors while elevating the margarita — treating it as a craft cocktail rather than a sidekick. That focus matters because it fills a niche: locals get a place that honors Mexican cooking and puts thoughtful, adventurous margaritas at the center of the meal. The result is a festive, welcoming spot designed for both special nights and casual gatherings.
