i like this idea - custard...i mean at first, i dont like to think about it, because custard has more eggs..and i am not an egg person...in any case...i really like the concretes which is similar to a dairy queen blizzard - custard with a mix in...i dont think there is much of a frozen yogurt craze there, so this is a great alternative. i ha to minus a star because although vegas it hot, i have been there when the weather is nice, and the custard seems to melt too quickly - and then i feel like im drinking a virgin egg nog at that point...but..try it and see how you like it..
