LUXEMBOURG, Sept 16 (Reuters) - Britain's Boris Johnson said on Monday that a Brexit deal was beginning to emerge, but the EU said he offered nothing to break the impasse during a visit to Luxembourg where he was harangued loudly by protesters and rebuked for trying to shift the blame.

"Don't make the EU the bad guy," Luxembourg Prime Minister Xavier Bettel said after a meeting with Johnson, describing the uncertainty over the timing and conditions of Britain's exit from the European Union as a "nightmare".

The British prime minister joined European Commission President Jean-Claude Juncker for lunch at the Bouquet Garni restaurant, an 18th-century building of bare stone walls and low ceilings in the medieval heart of Luxembourg.

A British official said their lunch included pan-cooked chicken oysters and butter-roasted pollock with creamy risotto.

Johnson was heckled from start of his visit with dozens of Britons - many of them retirees living in Luxembourg - booing, chanting and holding banners outside the restaurant.

The crowd and the booing swelled when he went on to meet Bettel, where at least 50 protesters waiting behind the gates created a scene that seemed out of place in the usually sedate centre of Luxembourg.

There were chants of "Fascist!", "Stop the coup! Tell the truth!" and "Shame on Boris", and the protesters played bursts of music that included the EU's "Ode to Joy" anthem and "I can't get no satisfaction".

Johnson was due to address journalists alongside Bettel in the courtyard after their meeting but left straight away, saying later that it wouldn't have been fair on the Luxembourg prime minister to hold a news conference amid a din of protests.

With less than seven weeks until Britain is due to leave the EU, Johnson has yet to reach an agreement with Brussels on how to manage the separation between the world's fifth-largest economy and its biggest trading partner.

"STOP SPEAKING - ACT"

Johnson is hoping a Brexit deal can be clinched at an EU summit on Oct. 17-18.

"Yes, there is a good chance of a deal, yes I can see the shape of it, everybody can see roughly what could be done," he told reporters after his Luxembourg meetings.
