We’ve spent more waking hours than we care to admit standing in line at Anna’s Taqueria. For those who’ve found themselves in a similar position, just a head’s up: If a lunchtime burrito is on your agenda, better get in line about … now. In honor of their 15th anniversary, they’re giving away free treats today (and on the 15th of every month). Today’s giveaway is horchata (that sweet, addictive almond milk libation) and Jamaica (a boiled flower petal drink). You might also consider entering for the chance to win a burrito party for 50 of your closest friends.
