*Disclaimer, been over 8 years since I lived there but I think this is accurate!
Second lark lane. Keith’s wine bar (took my now wife there at end of first date!) for some nice non pricey grub and, unsurprisingly, wine – though its been a while since I’ve been there. Loads of other restaurants there also.
If she’s missing Finland then you can call the Scandinavian seamans church and book a nice sauna! They might also have bunks if you’re struggling for hotels.
Hope street has some nice restaurants (60 hope st, London carriage works) and I’ve enjoyed a stay at the hope street hotel – well I proposed there! Liverpool is slightly unique in that it has two cathedrals – a catholic one known locally as Paddy’s Wigwam and the gothic Anglican one linked by Hope street.
The Tate gallery at the docks is good to go round.
Lastly, if she is interested in the Beatles or just wants to make her parents jealous then you could take her to penny lane. Again, there are some good restaurants and places to eat – penny lane wine bar and the Tavern Company (has some best breakfast award).
Blimey, I should get a job at the Liverpool tourist board!
