The Cambridge Tea House is a nice place. They serve Harney & Sons exclusively and have some exquisite bakes goods. Their “cream tea” is not at all British. (I have yet to find an authentic British style scone in the USA). I am really glad that this place exists here in a remote outpost of football fields and stadia.
Some suggestions in case they read: try to serve the tea before you serve the food. We ended up eating all of our food (we were hungry) before the tea even arrived.
Consider warming the mugs/cups in which you will serve the tea,
Ideally you will bring out the pots of tea first, with warmed tea cups and then bring out the food five minutes later so that the food and tea can be coordinated. Experiment and see if you can make a real British scone—I am sure it’s not that difficult. If your scones were British I’d probably stop by all the time!
