neh.........they are totally different. The type of rice you dined out at resturant with sticky traits might be Japanese type of rice which meant it contains more water and round shape or rice grain and the size of rice is not very too big as southern asian rice such as Thai or veitname. This is type of rice is high class of rice.
But there are really having sticky rice which got two types of grain one is long grain and the other is round as pearl and dmuch tiny than the previous one. This type of rice we usually use it as any kind of deserts such Japanese Omochi with red bean paste dumpling wrapped by sticky rice pastry.
If you would like to make the one exactly the same as the Chinese resturant does, simplely go ask the waiter or cook there what the brand name of the rice they fix, then go to any asian grocery store to buy the exact the same of rice and fix it at home by yourself.
Another top one rice( I guess the chinese resturant wouldn't use this expensive type of rice at all for customer cuz too expensive) I would like to recommand you to try is Konishiki rice which is usually for sushi rice which even when it is cold the texture still sticky and contain a lot of moisture and tender to chew.
Please do not buy any cheap rice, cuz they taste yuck for a picky rice stapler like me... hahahha.. The best is any brand of rice from Japan. Their rice is the best of all in the world.
Also Pakistan or Indian rice for me is too tough and too dried to swallow.
