we got Rita's Water Ice here, too....I think they started in Philly. Very yummy. My fav is passion fruit gelati, which has vanilla custard on the bottom, then passion fruit water ice, then topped with a swirl of more vanilla custard. Like this:
As far as DQ, I go for either the Snickers Blizzard
or the Pecan Mudslide
or the Peanut Buster Parfait
We also have a local Coldstone, but along those lines I prefer the local Maggie Moos...very rich and creamy ice cream and whatnot
