This advertisement for the Cambridge Hotel, from a 1950s guide to the town, seems to imply that the restaurant (and the cocktail bar?) are much older than the rest of the building. In fact, it was built from scratch in the 1860s. Before that, the area was commonly called ‘Mud Town’ which implies that there was nothing much there of note, except a tendency for poor drainage when it rained.
Even in the 1950s I think travellers would probably have hoped for more than ‘hot and cold’ water in every room (that is, a wash-basin and communal bathroom along the landing) and central-heating rather than a gas fire. Perhaps people stayed at other hotels locally if they wanted luxury?
