People were invited to dine on a 500-metre long table set on the Charles Bridge where around 2,000 seats were set up.
Those who wished to attend had to reserve a space in advance and were encouraged to bring their own drinks and food.
Czechs danced and sang – without any social distancing in place – as they listened to local musicians perform at the celebratory event.
While the World Health Organisation (WHO) has warned the pandemic is far from over, one cafe owner in Czech Republic said a lack of tourists in the city meant residents were able to gather to celebrate the easing of nationwide lockdown restrictions on Tuesday.
The Czech Republic has eased restrictions to allow public gatherings of up to 1,000 people and for a month restaurants, bars and pubs have been allowed to serve people.

One diner, Eva Nesverova said the party was about “enjoying life” now that “things are going more easy with Covid-19”.
Ondrej Kobza, owner of a cafe in the city and organiser of the party which was fully booked, said the event was about community.
He said: “The bridge is a good metaphor, different people can gather.”
Mr Kobza addeed: “We want to celebrate the end of the coronavirus crisis by letting people meet and show they are not afraid to meet, that they are not afraid to take a piece of a sandwich from their neighbour.”
Galina Khomchenko-Krejcikova, who attended the party after finding the event on Facebook, said: “I just finished a night shift so I didn’t have time to prepare anything.
“But we brought some wine and snacks we found at home.”
In total, 349 people have died after contracting coronavirus in the Czech Republic and fewer than 12,000 people have been infected with the disease.
But just last week the country reported 260 new Covid-19 cases, its highest tally since April 8.
