I was going to edit my hastily-written post for gelato but couldn't be arsed!
Agree on the service, typically Italian, orders taken without a notepad and something always forgotten.
It's called Montagues, just as it has been for around 30 years now >https://montaguestexmex.co.uk
Agreed, it's always decent in there, and I prefer it to Liming.
We've not tried it yet, but opposite Fiordilatte is The Burger and Brownie Co, and it won't cost you quite that much > https://www.theburgerbrownieco.com
If you like pizza, Fiordilatte on Warwick Street is excellent and very reasonably priced. they do a few pasta dishes if pizza isn't your thing.
It's where I ate last Sunday lunchtime as it happens.
