  • Owner, hostess and wait staff are super friendly! We come almost every weekend for breakfast and love it. The feta and spinach omelet is superb!
  • Just a caution they dont serve breakfast all day.
  • Very disappointed!!
  • The food is great, I usually come for breakfast and dinner. I always get the steak and eggs for breakfast, some of the waitresses even know what I want before I tell them. Love this place
  • Great little diner!
  • Cosmos is a Wilmington staple. Love bringing the family here.
  • Excellent Greek food.
  • Good variety of Greek dishes.
  • Always get good food and plenty of it.
  • The quick service and the big breakfast combo.
  • I love their eclair!! They have the best eclair you'll ever eat!!
  • Food is good. The service is terrible sat there for 15 before anyone brought a menu. Then had to wait another 10 minutes before anyone took our order. Happened 2x all white customers served first.
  • Breakfast, Greek

  • Love the food here. Been coming here since I was wittle :-)
  • Cosmo's is always great for breakfast
  • Been coming here for 20 years. Great Greek diner. The food is amazing.
  • Make sure you try the vegetable soup!
  • The fried chicken and the turkey dinner are the greatest!
