How about planning a special evening where you cook him a homemade dinner of local cuisine? You could try preparing a dish that he hasn't tried before, or you could recreate a dish from his favorite local restaurant.
To make it even more special, set the table with candles and romantic décor, and maybe even dress up a little. You could even have a bottle of his favorite local wine or beer to pair with the meal.
If you don't feel confident in your cooking skills, you could also consider booking a reservation at a local restaurant that serves his favorite cuisine. Try to find a restaurant that has a special Valentine's Day menu or romantic atmosphere to make it a memorable experience.
Or you can get him a star map with the date of your first kiss.
