Anything fun to do tomorrow evening alone in London?

[Whatsnewwithyou]

Usually when I'm alone in London for work then in the evening I'll either go to the theatre or to a museum late opening. However there's nothing I'm dying to see at the theatre at the minute that I haven't seen already. As it's a Monday night I haven't found any late openings at museums. I don't really want to sit by myself in the hotel room. So AIBU to ask what I should do? I woll havd dinner somewhere but then what?

I always go on the boats down the Thames but that maybe just me , they are quite nice at night seeing things lit up.

What did you do in the end? Hope you had fun whatever it was!

I'm sorry to say I didn't really do much...I had dinner at a nice restaurant and was all set to go on the Westminster walking tour but I have a bad cold at the minute and in the end just didn't feel up to it :-(. Usually I love coming to London so it was a shame to waste it but just one of those things.

Currently sitting in my hotel drinking Lemsip and trying to get ready to face the day. At least I have lots of great ideas for next time!!
