Gift ideas please

[Confuzzleduzzled]

I’m staying abroad at DB1’s house for 3 nights to celebrate DB2’s 50th birthday.
I can’t think what to buy as a thank you gift for DB1 or a 50th gift for DB2.
DB1 loves cooking and music and quirky stuff, DB2 is into computers and music and geeky stuff. Both need to be transportable in my luggage and can’t be fresh food. They live in Europe so no point bringing wine as it’s better and cheaper there.
Any ideas please?

• pay for a meal out for you all
• Theatre or other local show
• Voucher for them to go out locally
• hamper bought locally of cooking ingredients
• photo calendar from your local area/where they used to live
• British tea/sweets
