My husband is 60 next week, and he is the kind of man who hates a good knees up. I have tried various ideas to shake him out of denial of the big-0. I even suggested Silverstone f1, then just a fish restaurant we hadn't tried, or posh afternoon tea. The best I managed in the end was a booking at the local Turkish restaurant - nothing new. In the end one has to shrug and say "whatever!".
For mine I did what appealed at the time, and invited any lady friends who were free, who ended up being people I had met in my 20s, 30s, 40s, 50s (just 10 of us in all) - and I treated them to a cheapo but delicious lunch at the local Italian, follow by an M&S chocolate cake I had taken along. Enjoyed by all.
