That's a real shame - we could do with a good Thai restaurant round here.
We went out a couple of Fridays ago with family members we had staying - we had to wait for seats at the tapas bar (which has enjoyed someting of a renaissance recently). With Babur and Le Querce usually being full, HOP could easily, I think, support another restaurant.
(Tapas bar has been lovely the last few times we've been).
