Atatürk Olympic Stadium

The Pelit company has made chocolate since 1957. This small museum is dedicated to the history of chocolate in Turkey and also features numerous chocolate sculptures.

This district lies between the "little lagoon" of that name, and Ataturk airport. It houses the Halkali Railway Station. There are lakeside areas for strolling and cycling, and there is a 16th-century stone arch bridge over the creek that connects the lake to the sea, but you wouldn't make a special trip.

Aquarium where you walk through transparent tunnels underwater. It's small compared to Istanbul Aquarium in Yeşilköy, an hour will be plenty, and their combi-tickets with Madame Tussauds (in Beyoğlu) and Legoland indicate their target audience.

Much bigger aquarium than Sea Life, with over 1,500 species. 3 cafes and large parking lot.
