There are certain unwritten rules in life. Some examples:

—Always hold the door for people.
—Never stand at home plate and admire your home run blast.
—Always seek out drinks served in skulls. Even if they’re in the suburbs.

Regarding that last one, may we introduce you to Pepita, a tiny Mexican cantina from Mike Isabella that happens to offer 55 different cocktails. It opens Thursday in Ballston.

First, look at the slideshow. Then, look at these numbers.

3.3: Miles from Key Bridge to here. See, not that far.

10: Seats at the concrete bar.

119: Different tequilas and mezcals visible from those stools.

20: Housemade syrups, tinctures and bitters sitting on the bar, like habanero, curry and barrel-aged raspberry.

4: Margaritas on tap, available by the glass or by pitchers shaped to look like skulls. (Yes, skulls.)

44: Seats at the patio, which will more than double capacity when it opens around Labor Day.

3: Tacos on the menu, including smoked carnitas and grilled avocado.

12: Hours per day that they’ll be open (longer on weekends).

12: Hours per day that they’ll have some sort of happy hour special going on.

11am just got happy.
