There are lots of 2 person tables but they are very close to the other 2 person tables, maybe 6 inch gap between. The ones by the windows and walls are two 2 person tables, so effectively tables for 4, and in the middle of the room there are runs of tables, so you might have close neighbours both sides.
The difference from sitting on a larger table, is that you won’t be seated and served at the same time, so it’s up to you whether you want to chat to them or pretend they aren’t there. You won’t be able to have a private conversation and you’ll be able to hear their conversation.
If you opt for Select dining, which is where you can just turn up at the dining room at any time during opening hours, the first two nights are busy, especially the first night. The member of staff on the door, will ask you what size table you want. It’s likely that if you agree to share a table you will be able to go in straight away or have a shorter wait than if you ask for a table for 2. You’ll probably be sent away with a buzzer which will buzz when a table comes free.
After the first two nights it settles down and you may not have to wait at all regardless of what size table you choose.
