Consider us corrected. We'd always assumed that "National Margarita Day" was Cinco de Mayo. In fact, it's Tuesday — Feb. 22.

We're not usually ones for arbitrary national holidays (Sweetest Day, Oct. 14, being our least favorite) but this is one occasion to celebrate. To assist, we've compiled our highly scientific, oh-so-personal, curated list of the best margs in town:

Pico's - Pico's "MexMex" on Bellaire Boulevard makes margaritas with perfect texture — ice-cold but not too frozen to slurp through a straw — and served in a neon shaker for easy self-serve.

The Original Ninfa's on Navigation - The Tex-Mex mecca sold 87,000 Ninfaritas in 2010, and the house margarita is still one of the strongest in town. And now, with a new patio bar and the help of Anvil's Bobby Heugel, Ninfa's new winter-spiced margarita also makes our list.

The restaurant formerly known (like, last weekend) as El Patio - Now re-branded as Xuco Xicana with a menu updated by Beaver's partner and chef Jonathan Jones, the blue margaritas (rumored to include Everclear) are still lovely — and lethal.

El Tiempo - The Laurenzo family's trio of El Tiempo Cantinas are famous for two things: Fajitas and margaritas. Both are done so well that they inspired a birthday theme for one CultureMap staffer's dinner this year (hint — it was me): "Fajitas, Margaritas and Banditas." Ole!

Armando's - Theres a risk in sipping Armando's margaritas. It's that after a few of them, your behavior won't be as refined as your surroundings. Armando's margs are stiff and, by some accounts, so is its ambience.

We happen to love the place, but if tequila makes you boisterous, beware.

The Grove - The swanky downtown restaurant adjacent to Discovery Green mixes an incredible ginger margarita. I first sampled it at The Grove's now-private TreeHouse bar, but a call today confirms that it's still on the menu, and not to be missed.
