Grey Goose, but I'm too cheap to buy it often. At home, we generally just have Smirnoff. I order the top shelf stuff if we go out for a special occasion.

Wohoo for Titos!! So pleased to see it's gaining great popularity;) But seriously, OP, it's the most smooth-tasting vodka I've had. (Which can be dangerous, so proceed with caution!!)
Also please get some blue cheese stuffed olives. So good.
There is a place in the Orlando area that serves these fantastic martinis with blue cheese stuffed olives. And also this amazing fried Asiago cheese stuffed olives appetizer. I don't think the rest of their food was that great, IIRC, but I could have sat there and eaten olives and drank martinis all day long.
