Batam trip on 25th July to 28th.
Rented a scooter for whole trip. Went to eat at Tg Piayu Rumah Makan Seafood Jawa Melayu. Very cheap only around 300k for 2 pax.around 35 mins ride from Nagoya.
Also went to One Seafood Marina on 2nd day which is somewhere enar Bt Aji. The cheapest sea humm and gonggong ever. 1kg for 40k to 50k cooked depends on cooking style. 3rd day went to Next Level Koffie and Beachfront Bar at Bengkong. Very nice place to relax and chill by the beach. Have horse riding too during daytime.
