Cosmos is a good value for the money, conveniently located next to the Stony Brook train station and the State University of New York at Stony Brook. The food is Greek-American specialties that one expects to find in such a restaurant in the US. Although many dishes are far from traditional Greek, there are several that capture the Greek spirit, although all of them leave a good taste impression, and definately are worth the money given. The restaurant atmosphere is casual, as would expected from the proximity to the university. In conclusion, nobody will regret visiting this restaurant and is one of the best values around the university.
