First experience was great.
It is a franchise --and offers some Greek specialities.
Service is present, courteous and fast.i didn't have to request to get something. The waiter on that night was the one requesting me whether I needed something and proceeded to get it done on the go.
Food was not bad. The establishment is not cheap --we had enough meat for two for under 30$. For instance , the calamari plate was not the best , but it was good and not oily , this is a big plus as you don't feel completely drained and dead after your meal. The souvlaki pitas had enough meat and plenty of sauce for one to be satisfied. Their fries tasted like potatoes chips cooked in the oven--so goood. As for the Greek salad , wasn't great but it wasn't bad.
Anyway , I felt like the reviews for the restaurant did not do justice. Indeed, marathon souvlaki is an excellent restaurant with Greek specialities, if is affordable and you feel like a customer that they want you to come back for another visit , which I personally will.
