When you go for brunch, there is a buffet and your server walks you through the different sections explaining what everything is an making recommendations. Then they walk you through an area that has the hot food you can order, with sample plates made up so you can look at them.
Then you are free to help yourself to the buffet. When you are ready to place an order for the "hot food" or "entree", you let your server know, and they will make it for you.
I don't know about tea, we didn't try that.
