This is a Michelin-starred restaurant in Piraeus.
If you’re up for a splurge, I love the breakfast buffet at Le Grand Balcon in the St George Lycabettus hotel. It’s located in Kolonaki, an artsy upscale district with galleries and coffee shops.
If you like museums, the Benaki museum has a nice collection.
The Electra Palace Hotel in Plaka also has a nice breakfast. I prefer the location of the St George Lycabettus Hotel, but the Electra Palace is a nice place to stay. https://www.electrahotels.gr/hotels/electra-palace-athens/
