This one is just right

Jam, in Falmouth, is the perfect cafe. That's it on the left. The coffee is unbeatable, the ice creams are irresistible; the furnishings are reassuringly worn and scattily selected.
There's even a dog, an adolescent black labroador, who is quite stupidly friendly.
You can sit down, or stroll around listening to excellent music, flicking through the second hand CDs for sale, or browse the small but impressive selection of books.
Jam is one of the reasons I agree to take the 97 hour train journey from Paddington to Cornwall at least once a year, to teach on Univerity College Falmouth's professional writing course.
It's not really 97 hours, it just feels like it, especially when the air conditioning is set to Arctic and the buffet closes at Exeter so a small man with a calculator can count what's left. No, I have no idea why he can't just sell it instead. You'd have thought it would save some bother along the way, but never mind. Just remember to pack a picnic box.
It's a shame (for me) that Jam is 300 miles from my house, but maybe one day I'll have one like that within walking distance. In the meantime, I aim to recreate the Jam atmosphere in my front room. It's great for working, having ideas, jotting down lines of dialogue, reading books and generally reassuring yourself that life really is worth the bother.
Please do go there, and feel free to recommend your own favourites.
