Dave's Cosmic Subs is a Cleveland institution. The shops combine great sandwiches with classic 1960s rock music and culture. All the subs are dressed with Dave's signature sauces. The first Dave's opened in Chagrin falls in 1997. Now Dave's Cosmic Subs can be found in 13 locations, including Atlanta, Georgia. This one is in Coventry, across the street from Marc's. This Dave's Cosmic Subs delivers.
