This is really the only real Lavazza option in town. Great espresso. 

The place is owned by a young couple. It's a hybrid of a cafe and restaurant. They do all the cooking themselves. Superb breakfast plate. But from the opening to the closing hours there are all kinds different food choices, Turkish or international fare, hamburgers sausages etc. They all taste good, presented in a pleasant manner. Different kinds of beer and cocktails are on the offer all day long. Great lemonades and other cold soft drinks during summer.

 Datca is not developped in service sector compare to the rest of Turkey. And while the town is full of places that can satisfy the local taste or tourists from Ankara with provincial attitude, this is the place that can satisfy travellers from Istanbul.

 Location is great ! Right by the water. Superb views of Datca bay. You can even jump to the water while waiting for your order. Kids and pets are more than welcome. Free wi-fi. Clean bathrooms.

 Very likely that once seated, you'll have very hard time to leave. V/MC welcome but no AMEX. There is an ATM less than 100 meters from Cafe Inn.

Very easy to find. Right on main drag. Ataturk caddesi 51. Phone number is (0252)7129408. You can come from the street side or pedestrian only seaside walkway. (if you are in the marina: it's the next bay but very close. You have to walk 250 meters towards the town)
