Larger-than-life inflatable Santas bob outside a Christmas tree stall, enticing customers into one of the few places allowed to stay open in the Netherlands, which is now wholly locked down.
The window-shopping students I met responded to the closure of bars, restaurants and all non-essential shops with frustration and resignation.
It feels like a really bad deja vu, one told me. His girlfriend is finding it difficult to accept the pause in what would normally be a packed festive calendar.
George, a chef in The Hague told me he will be going into work tomorrow but only to throw away all the fresh food they were planning to serve.
The Dutch PM described this lockdown as an "unavoidable" response to Omicron.
But his critics point to what was perceived by some as the mismanagement of the Delta strain and relatively slow rollout of the booster vaccination programme. The over-60s have only just been invited to get their extra shots.
Across Europe this Christmas, coming together is becoming harder, and riskier, than anyone would have wished.

Covid passes are issued to people who have been vaccinated.
"We think the Covid safe ticket is discriminatory," one protester told Reuters news agency, adding that Belgians should not have their "freedoms" curtailed for refusing jabs.
Police estimated that about 3,500 people attended Sunday's march. Many waved flags and carried signs reading "I am free, you are free, we are free" and "no to mandatory vaccination".
Belgium has reported almost two million cases of coronavirus and 27,895 Covid-related deaths since the start of the pandemic.

The chief medical officer says Omicron could be the most dominant variant in NI by Christmas and Deputy First Minister Michelle O'Neill has said it will hit the country "like a tonne of bricks".
Health trusts are operating walk-in booster vaccination clinics, with up-to-date information on each trust's social media platforms, the Department of Health says.
Over-30s can currently book a slot online, external, while bookings are expected to be made available for people in the 18 to 29 age group in the next few days.
A further 82,886 coronavirus cases have been reported in the UK - as the more transmissible Omicron variant continues to surge around the country.
That figure is down on yesterday's total, which was over 90,000, but significantly up on this time last week
There have also been a further 45 deaths recorded within 28 days of a positive Covid test.
Image source, EPAWales is likely to see a "tsunami" of Covid cases, according to a public health official.
Current plans to tackle the Omicron variant in Wales may not be enough, a leading government adviser has said.
Public Health Wales' Dr Giri Shankar says further restrictions could be needed.
He adds that Wales is "likely to see a tsunami of cases" in the coming weeks.
The first minister has already said that other restrictions could be introduced while nightclubs will close from 27 December.
With the furlough scheme having come to end in September, questions have been raised as to how nightclub staff are going to paid.
But Mark Drakeford says: "We will look as a government to see if there's any help we can give that sector to support people who would otherwise be laid off.
"We are certainly not gambling with anybody's livelihood. We've put £60m on the table."
Image source, EPABooster jabs given in England have hit a record high, with more than 830,000 administered on Saturday.
A record 906,656 vaccine doses were given in total, including first and second jabs, NHS England said. Of those, 830,403 were booster jabs.
A rate of around one million a day is needed if every adult is to be offered a booster jab by the end of the year.
Image source, ReutersMore than half of new Covid-19 cases in the Republic of Ireland are believed to be Omicron cases, meaning it is now the Republic's dominant variant.
Ireland's Chief Medical Officer Dr Tony Holohan urged people to get vaccinated and reduce their social contacts.
He said it had taken less than two weeks for Omicron to become dominant in Ireland, which revealed "just how transmissible this variant is".
A further 5,124 confirmed cases of Covid-19 were reported on Sunday.
From Monday, hospitality venues, cinemas and theatres will have to close at 20:00.

Cabinet Office Minister Steve Barclay will chair a meeting between the government's emergency committee, Cobra, and the leaders of the devolved nations at 17:00 GMT.
Confirmation of the meeting comes shortly after the Health Security Agency announced that 12,133 additional cases of the Omicron variant had been reported across the UK.
This brings the total of confirmed Omicron cases in the UK to 37,101.
