For those not from the area: Diddy Riese is a legendary cookie store in Westwood, right off the UCLA campus. They have awesome fresh baked cookies that used to be $0.25 (now $0.35) and create-your-own ice cream sandwiches for $1.00 (now $1.25). Great eats, great price. If you are ever in the area, stop by and try them, you won't be disappointed. Just be warned, the lines are long if you hit it at the wrong time.

For those that are familiar: I haven't been in a couple years, but there's a work function tomorrow that I want to bring Diddy Riese to now that I live in the area. What are the must haves if I get a couple dozen or so? My personal fave is the cinnamon sugar. I seem to remember lots of people raving about oatmeal raisin and macadamia nut, both not favorite cookie types of mine, but they may do well served to the large group.
I appreciate any help and hope I inspired some of you to enjoy the greatness that is Diddy Riese.
