How much did you pay for your last meal out? And did the dish include a mix of cutlet, sausage, kidney, bacon and egg?

A recent post from Lonely Planet writer Fionn Davenport has got Irish Twitter talking. The tweet features a photo of a menu from Dublin's Gresham Hotel from 1972, listing some interesting meals and jaw-dropping prices.

Fionn joined Cormac Ó hEadhra on Drivetime on RTÉ Radio 1 to discuss the menu in detail. And although the items on offer give an interesting peek into the nation's eating habits at the time (best of luck to any vegetarians in the 70s), it was the prices that caught Cormac's eye.

According to the menu, a cheese omelette in one of the capital's finest establishments would set you back 35p while a schnitzel of veal would take 98p from your pocket.

Using the CSO inflation calculator, Fionn determined that "a pound in 1972 is worth €14 in 2020". You can test out your math skills by having a look at the menu in detail below...

Unsurprisingly, the hotel's prices have changed a little in the past 49 years. In 1972 a beef burger and fried egg cost 40p, while today's Gresham's beef burger with smokey bacon, cheddar cheese and fries comes in at €13.95

Before you start longing for days gone by, though, Fionn reminds listeners that the quality of food has changed over time too:

"It's worth pointing out that the coffee of 1972 is not the coffee that we might know today," he explains. "In fact, I would wager any amount of money that it was a spoonful of Maxwell House or Nescafé stirred into a cup, add water from the kettle, and that's your cup of coffee."

"1972 is an interesting time in Irish culinary history, it is the dark ages seen from the view of the 90s and afterwards," he laughs. "The vast majority of Irish people would never have eaten in a restaurant or they may have done for a special occasion - for a communion or a really important birthday."

"The menu reflects a time when restaurant dining was not common place, but it's also an indicator of how conservative Irish culinary tastes were," he continues.

This little slice of food history set Twitter ablaze with memories of days gone by, the Irish diet, and obscure 70s starters. You check out some of the best tweets below:
