After reading the comments on this forum about the noise outside the Question Bar (and being a HOP resident in close vicinity to the Old Bank site) - I am not sure I'd like a gastro pub there.
A restaurant would obviously be preferable to a Domino's but in this climate, would it really be able to make enough money to survive? Old Bank was around £30 a head inc booze if I remember rightly, and they obviously struggled.
Babur is an exception I think, as it has built its reputation over many years and is a destination restaurant, and Le Querce offers excellent value but is a much less prominent location so the rent is possibly cheaper (I may be wrong on this)?
