    The octopus is absolute perfection. The menu is saturated in real Greek food, and I was able to tell the ingredients are very fresh. Service is excellent, which is hard to find anywhere nowadays. Every dish I’ve had so far is a 10/10. And they have a huge menu so that’s impressive.

    THASSOS Greek Restaurant is without a doubt the best Greek Restaurant in IL. The food is Authentic and a culinary delight. They also offer a Wine selection that is Fabulous. There are some Wines on the list that are not easy to find. The atmosphere is relaxed & upscale. The service is professional & they are extremely knowledgable on the menu & Wines. You will often find Nick or Natasha the owners checking to make sure your dining experience is the Best.
