Tis a shame that 'Sundays are crap' ... that's the only day I can really punt!
Working during the week I don't get home until 7pm, so by the time I done research and booking it's too late to go out to do anything, and to get back home again. Saturdays (for me) are usually full of things that I can't do during the week (shopping, 'life', etc), leaving me with just Sunday.
But, that explains why I seem to have limited success.
On rare occasions I can get away from work early, but I never know when that is going to happen, so I can't book anything in advance.
I usually try to plan something for the Monday on a bank-holiday weekend ... visited Sala Thai last weekend ... but I think I will be going through a lean spell until Xmas.
