Eating dinner alone is a privilege, not a burden. You become vastly more interesting to the staff and you have an experience that's all about you.
When I was living in Budapest and working for a company in London, I'd spend about a week of every month living in the company flat just off Kensington High Street. Alone. (generally)
It's a rather swanky area. I was making good money. And dining alone was fun sometimes (especially at wagamama, because you are never alone at wagamama!), but after a while it got a bit lonely.
So I would walk up to random people that caught my interest, and invite them to have dinner with me, on my tab.
Actually ate with two mildly famous supermodels. A young couple from Holland. London locals, etc.
It was fun and fascinating!
