A North Texas legend in Tex-Mex dining, Mariano’s Hacienda is making festive waves this year by opening on a day it’s usually closed. On Monday, May 5, 2025, Mariano’s Hacienda and its sister restaurant La Hacienda Ranch will open from 3 PM to 9 PM for a one-day-only Cinco de Mayo celebration featuring exclusive specials.
Few drinks are more iconic than the margarita, and few places are more fitting to enjoy one than at Mariano’s — where the world’s first frozen margarita machine was invented in 1971 by founder Mariano Martinez. Today, that machine resides in the Smithsonian, but the original recipe is still served daily at the restaurant that started it all.
For Cinco de Mayo only, Mariano’s will feature their signature Original Frozen Margarita and Original Margarita On the Rocks for just $9 — all day.
Whether you’re a fan of the classic salt rim or prefer yours with a twist of lime, this is a rare chance to enjoy the iconic cocktail where it all began.
To accommodate the celebration, Mariano’s Hacienda and La Hacienda Ranch will open for special hours from 3 PM to 9 PM on Monday, May 5, 2025 — an exception to their usual Monday closure.
