During our visit to Athens, there was a restaurant that we ate at repeatedly. When we slow-travel we like to find a good restaurant near our hotel and eat there repeatedly, so that we are regulars and have something familiar to go to during our stay. In Athens this was Melilotos Restaurant. It ticked all the boxes:

10minute walk from Syntagma Square, where our hotel was located
Super yummy, fresh food. The salads are amazing.
The interiors were beautiful, while homey

Melilotos reinvents the traditional local dishes at decent prices. The pistachio-coloured dining room has been described as neo-rustic. It was conveniently near Syntagma Square and our hotel & served excellent salads and grills using super fresh & the highest quality ingredients!
