Ever since its inception in 1998, Cosmo’s has never strayed from the principles on which it was built!

Cosmo’s IS homemade Italian cuisine, freshly-baked bread and fine-tasting wine from our bar offered in the best affordable quality! Several nights a week we also hold theme nights which include “Noodle Night,” “Ravioli Night”, “The Sunday Night Spaghetti Feast!” and don’t forget we’d love to cater your event.

Cosmo’s IS hospitality personified! We pride ourselves in serving you with the utmost enthusiasm and concern! It is our commitment to excellence on a nightly basis that sets us apart from our competitors! Our dedication to hospitality truly sets the foundation for our restaurant!
