For those in LA - a couple ice cream recommendations:

Dr Bob's -- I think this may be the best ice cream I've had outside of stuff made in-house at nicer restaurants (and I've seen them use Dr. Bob's as well in the LA area, though usually they'll use a preferred local ice cream artisan guy if they don't make it in house). His chocolate flavors use only Scharffen Berger chocolates, very good stuff.

Mashti Malone -- Persian ice cream - flavors such as Rosewater Saffron (many variants of the Rosewater flavor, apparently one of the top dessert flavors in the Middle East) and Orange Blossom. The $2 sandwich is a scoop of their ice cream pressed between 2 thin wafers then rolled in pistachios.
