Has anyone been to the Japanese restaurant Sakura?...?!

I've been there a few times and the food is amazing! Well my question is, does anyone know what sauce the chef uses in the fried rice? He also uses it as a side sauce in that little dish. It has a creamy texture to it and it's a peachy cream color. Does any one know what it's called, or what's in the ingredients so that I could make it myself?
Thanks in advance to everyone who answers!
