When our Brit friends moved back to Canada last fall, TH at the airport was the first stop they wanted to make after they cleared customs/immigration.
I have no yardstick to measure it by, because I've not been to the UK, but they aren't the first British friends of ours who claim that TH is better than anything they'd ever manage to get in the UK. Eh, it made them happy, so we stopped before taking them to their new home.
