Thank you for your last corrections!

Question

Can you help me check these sentences, too?

1) For lunch I went to my parents' house (or is it better: I had lunch at my parents' house?)
2) For the rest of my holiday(S) I did my homework (or I spent the rest of my holidays doing my homowork)
3) I used all my pocket money giving presents (or on Christmas presents?)
4) My team and I went to Geneva (or I went to Geneva with my football team?)
5) We went out in the most famous streets of London (or We went out for a walk in the most famous streets of London)
6)For my dessert I had chocolate cake (or a chocolate cake or a slice of ..)
7) How would you comment on this mistake: I ate different Christmas dish. Them object must agree with the verb (??)

Thank you

Answer 1

I had lunch at my parent's house is more conversational.

It is just one holiday. This one would be better.
I spent the rest of my holiday doing my homowork

I used all my pocket money on Christmas presents

#4. both are fine.

We went for a walk in the most famous streets of London

For my dessert I had chocolate cake

7. I ate different Christmas dish

You didn't eat the "dish". You can say, For Christmas dinner I ate .....which I had never eaten before.
