National Margarita Day is Friday (Feb. 22), which means bars and restaurants throughout the city are slingin' margaritas on the cheap. It's a glorious day, a little hint of summertime to get us through these last few weeks of gray days before warmer weather begins to show its sweet, beautiful face. We compiled a list of local spots that are offering drink specials for the holiday so you can celebrate without breaking the bank. ¡Salud!
