Rita's Water Ices closes down in the winter, which is a shame because there is no packaged sugar free ice that is even close. I could eat the Green Tea flavor every day. Also good half and half with the mango or pineapple flavor.
And Meltykiss - also the green tea flavor. I wish I could buy it locally (although it's probably a good thing I can't) We get it sent from Japan by Jlist, and they can't mail chocolate in the hot weather.
