Our story

Onassis Greek Taphouse + Kitchen opened in May of 2021 and is owned by Chef Kostas Lazanas. The origins of Onassis can be found in a little Greek restaurant located in the neighboring city of Rowlett called Opa! Greek Taverna. Kostas started Opa! back in 2013 and out of tremendous support from the local community, was able to start Onassis in Rockwall.
