Friends- cost of meeting up

Hi,

I have a friend who when we meet up (one one one) always want to eat in restaurants. I know this is lovely, but it gets expensive and especially this month.

We tend to meet after work, do you have any ideas for cheaper ways of meeting up? She doesn't like pubs- so a cheap Wetherspoons won't do.

I have another friend and we just go for a walk- followed by coffee.
