Ok!
Betty's in York is insanely busy all year round. I don't know if they take bookings - suspect not - so you have to queue up. It wasn't too bad when we were there, we were only queuing for about 10 mins, and they give you the menu so you're all ready to order when you sit down.
You can order any tea/ cake/ snack combo that you like, or you can have the afternoon tea, which costs £16 per person (I think) and consists of:
4 small sandwiches each (ie one round, but you can mix and match fillings)
One fruit scone with clotted cream and jam each.
Three little cakes each. When we were there these were a tiny fruit tart, a lemon macaroon and a square chocolatey cake that I had to donate to DP as I had hit the wall by then.
Pot of tea of your choice and pot of hot water to refresh it.
This is all served on a traditional cake rack thingy, and every single bite of what we had was utterly gorgeous. Even the sandwiches (I had egg ones and ham ones) were somehow nicer than any sandwiches I'd ever tasted before!
It did cost a lot but it really fills you up so there's no need for an evening meal later. Also the atmosphere is so lovely, looking out onto the square, and the service was excellent too.
You wouldn't go every day but for a treat, well it was the nicest I've ever had. They have one in Harrogate too, which I assume offers the same prices, food and service.
