Good advice, ta.
I think the fact that you feel all warm and cosy after a punt is a good thing (as long as you don't start the whole "she actually liked me" thing) - but there's nothing worse than the opposite anyway, feeling you've just been entirely unwelcome.
I rarely go back for seconds, so regardless of how good it is it'll probably be a one-off (I live away from London now too, so my opportunities are limited meaning I like to try different options whenever I'm there, and there are plenty of apparent good 'uns that I'm yet to try). Nice though to see that pretty much without exception, the reviews are positive for Adele, meaning it's as close to a guaranteed positive as you're ever likely to get with someone you've not punted before.
