Cafe Slavia was built in 1881 at the same time as the grand National Theatre at the river end of Narodni. On the other side of the street and also fronting the river Vlatava, its purpose was to cater for theatre-goers.
Customers included Czech composer Bedrich Smetana, but the Slavia became highly popular with writers - particularly poets and dissidents - and it became known as the writers' cafe in Prague.
On a fiercely hot day of 31oC, when we could do little except drag ourselves from one cafe to another, this was our last port of call - a place to refresh ourselves after crossing the elegant most Legii bridge from Mala Strana.
A cream marble entrance hall with small fountain and gleaming brass Brasilia antique coffee machine offered instant relief from the sun.
Cafe Slavia's 19th century interior was replaced with Art Deco furnishings at the time of the first republic, and those fittings remain today - light marble, mirrors and dark wood, straight lines.
An exhibition of black and white photographs decorated the walls, waiters and waitresses in black and white huddled round an idle baby grand, white linen cloths draped over their arms.
We sat in a window, deliciously cool thanks to powerful air conditioning and broke our usual drinking habits - me ordering a bottled blackcurrant vitamin drink and Spooky, mint tea with honey. And roasted almonds to snack on.
These took almost half an hour to arrive, to the point I thought the waiter had forgotten. But when he brought them, the reason became clear.
Piping hot and oily, nestled in a bread basket, they'd obviously been freshly prepared and lifted straight from the oven. Their heat almost burnt my mouth - but the salt was a welcome antidote to the heat.
Other interesting items on the menu included Ice Cups of lemon ice cream with warm blackberries and mint, a Golem - sponge biscuits, mixed fruits, egg nog, whipped cream and strawberry sauce and Turkish coffee. A counter of home-made choclates and gateaux also greet the customer at the door.
I have to mention here that, as it was our last day in Prague, we'd just enjoyed a three-course lunch on the terrace overlooking the river at the Kampa Park restaurant, hence our ability to resist these temptations.
This also meant we couldn't finish the almonds, so I wrapped the remainder in a serviette and, hoping our waiter would not notice, tucked them in my bag.
Cafe Slavia partly prompted Rilke's Tales of Prague and inspired a poem bearing its name by Nobel-prize-winner, the poet and journalist Jaroslav Seibert. Unfortunately at time of writing this, I haven't managed to lay my hands on a copy of it.
Former Czech president, dissident, playwright and poet Vaclav Havel is also said to have plotted the overthrow of the Soviet regime in Cafe Slavia.
Songs and stories have all been penned - probably helped by the cafe's inspirational location, overlooking the river and its bridges with Prague castle elevated on the opposite bank.
But equally as famous as the scribes, is the cafe's absinthe drinker, a character portrayed in a large painting, with a green, will-o'-the-wisp woman floating before him like the absinthe fairy of
Baz Luhrmann's 2001 film Moulin Rouge, played by Kylie Minogue.
Absinthe is still on the menu, at 85 Koruna - around £2.50 a shot. If you order one, midway through the day during a typical Czech summer such as this, you're a braver person than I am.
