Tequila Bandera

Are any of you familiar with Tequlia "Bandera" Style? I just heard about it on a radio ad. Aparently, you are poured 3 shots (I assume chilled) of tequila, lime juice and this reddish sangrita (translation: cute little blood - kind of like spicy bloody mary mix). You can sip each shot in any order you like. Check out otherways to drink tequila (other than margaritas) on liquorsnob.com
