I've had afternoon tea all over the UK, and I have to say: The Dome is my favorite.
Afternoon tea is served daily (12p to 5p) in the Georgian Tea Room. Reservations strongly recommended, and it's £10 per person for your booking - that deposit amount will be deducted from the total bill on your visit. Booking online was easy, and there was an area to indicate any dietary restrictions (The Dome offers both a vegan afternoon tea and an NGCI [gluten-free] afternoon tea!) or special occasion information for them to know about in advance.
When we arrived, we were immediately greeted and sent upstairs to the beautifully decorated space where our table was waiting for us. The dress code? All over the place. A couple folks were dressed up, many more folks were dressed in jeans and t-shirts. So: don't worry about what you're wearing. While this place feels quite fancy, they're very welcoming!
At the time of visiting, the vegan afternoon tea was £29.50. Adding a glass of bubbles makes it go up between £5 and £7 (which really isn't that much when you think about it); you can also opt in for Tipsy Tea for £58 ("enjoy a cocktail with each tier").
Tier 1
My savory tier featured a vegan sausage roll, and three sandwiches: vegetable and hummus, sundried tomato and basil, artichoke with pea and mint. The sausage roll was golden-brown perfection, and I could have eaten several more of those unashamedly. The sandwiches, though bigger than I've experienced elsewhere, admittedly were just okay. Two of them tasted nearly identical (I'm assuming that whatever they're using in the veggie and hummus are quite similar to the sundried tomato and basil one); the artichoke, pea, and mint one however was light and refreshing and herbaceous!
Tier 2
I had a plain scone with vegan cream and jam. It was exactly what I was expecting: the scone was dense, but not dry, and delicious in subtleness!
Tier 3
My sweet tier contained a lemon tart, a raspberry mille-feulle, and a strawberry sponge. All very seasonally appropriate, very bright flavors. The lemon tart was my favorite, because it didn't hold back on the citrus flavor and the shell was "buttery"; I loved the abundance of fresh fruit in the mille-feulle and the crispness of the pastry; the strawberry sponge was pillowy and very pink!
I saw some people from across several review sites say there wasn't enough food for the price paid. I disagree. I thought it was the perfect amount (we were even encouraged to take home what we couldn't finish!) for a lunch-time meal. Also, the staff was lovely: they were humorous, they were attentive, they expertly communicated every single thing we were eating!
Finally, and if you can visit at the holidays: DO SO. It's magical.
