I need some ideas of a cool and relax cafe/restaurant name. Customers will remember easily.?

Oasis

At home

chillax shack

well try your last name or maybe even your first name

Good Memories

It would be helpfull to know what type of food you are planning on serving. For general fair you might call it the "Easy Street Cafe". For a cafe with open air dining you could call it "cool breeze"

Your name's-Cool Kitchen

cafe palace. very catchy and easy to remember

Under the Cabana
