You can get milkshakes with rice milk and rice dream ice cream at several places. My 11yo can't handle soy milk though she can handle Tofutti (there's some other ingredient she can't handle in every soy milk we've ever tried; we just don't know what). She's gotten milkshakes at 50s PTC, Sci-Fi Dine-In, Pop Century food court and POFQ food court. She chose not to get one at Plaza Restaurant but she was offered. I'm pretty sure each of these places does have Rice Dream ice cream; they definitely had rice milk (Pacific brand at the time). You know, I haven't heard if the rice products have changed or not; at this point I assume they're still Pacific for the milk and Rice Dream for the ice cream but with the other changes being made, there's no way to be sure without asking and I do recommend asking.
