Birthday plan ideas for partner

My GF's birthday is coming, I am looking for some plans that I can do. I would love to hear your ideas or plans you did for your partner on their special day. **PREVIOUS PLANS:** * Trip to Goa (Cake cutting at hotel, water sports, exploring North Goa castles, beaches etc) * Dinner at World of Veg along with shopping and cake cutting at night at home If it is some travel plan, I am okay with 20-30K budget. I am not of a person spending 10K on a dinner or something. The only criteria is money spend should be worth it. Travelling adds an experience for lifetime, so it is worth spending the money.
