We really enjoyed it and would do it again. We had tea, finger sandwiches (watercress & cucumber, tuna, egg salad, and PB&J for the kids), scones with raspberry jam and incredible Devonshire cream, and strawberries and cream. There was also a pastry tray that you could choose from, in place of the strawberries and cream, if you wanted that instead.
We ordered English Breakfast tea because it's my favorite, but there were many to choose from, and the menu had descriptions of each tea listed. We thought the sandwiches were very good; I don't care for tuna but I tried the others and they were good. My DH said the tuna was good. The watercress & cucumber sandwiches had a thin layer of cream cheese. One of my DSs doesn't like jelly (or jam), so they made him plain peanut butter sandwiches.
We had this as a late lunch one day and it definitely held us over until our late dinner that night.
