Indoor bday ideas for boyfriend

My boyfriends birthday is tomorrow and I’m going to decorate our living room with balloons and presents and cake, then we were supposed to go on a picnic but it’s supposed to rain all day. Saturday, we’re supposed to go to dinner with our friends, but we’re both feeling off, so we’re considering rescheduling.

What can I do for him tomorrow indoors to make his birthday special? An indoor picnic or nice dinner all dressed up?

Help pls 😭
