DO
Arch of Galerius and the Rotunda – These fascinating ancient landmarks are right in the middle of the city, so they’re very easy to check out.
Churches – You want to see some impressive old churches? Yeah, Thessaloniki’s got those.
Vlatadon Monastery – This place is a must-visit for the epic views of the city. It’s quite breathtaking.
EAT
Archontis – The spanakopita certainly isn’t gourmet, but for one euro for a seriously hefty slice, it’s way better than it has any right to be.
Bougatsa Bantis – If you’re looking for a tasty (and extremely unhealthy) breakfast in Thessaloniki, bougatsa is where it’s at. It’s dessert for breakfast, and it’s delicious.
Derlicatesen all Souvlaki – You can’t go to Greece and not try souvlaki.
Edessaïkó – The Greek comfort food they serve at this place was so cheap and delicious that I actually went back a second time. If you’re on a budget, this place needs to be on your list. And if you’re not, it still needs to be on your list — it’s so good.
Galyfianakis – The custard pie at this place was beyond delicious. It’s reason enough to visit Thessaloniki; it’s that good.
Gyros Aristotelous – The gyros at Gyros Aristotelous absolutely rocked my world. So damn good.
McDonald’s – McDonald’s in Greece is pretty boring — the menu is mostly just the usual suspects, though they do have a couple of vaguely interesting items.
Oi Pites Tis Voulas – There are a ridiculous amount of places in Thessaloniki that sell phyllo pies, and this was one of the better ones.
Terkenlis – This is a delightful Greek bakery that sells a whole bunch of seriously delicious sweet pastries.
Trigona Elenidi – Pretty much the only thing they sell here are trigona, a delicious pastry that’s kind of like a baklava and a cannoli had a baby.
