Mexi mart

The better Mexican martini... at Trudy's North Star. [Tuesday is topshelf at regular booze prices.]

Cazadores and then one with Don Julio --this one was with both Cointreau and Grand Marnier!

I think Drew at the link has it right:
2-1/2 ounces top-shelf tequila
1-1/2 ounces Cointreau or Grand Marnier or 3/4 ounce of each
1 ounce fresh orange juice
1 ounce fresh lime juice
2 ounces S&S Sweet & Sour

there is still a splash of Sprite or somesuch though, I've done it that way and had success.
