Puns make great playful suggestive trademarks.
A recent piece on MSN Now features photos of some great such names. For example:
– MERCHANT OF TENNIS
– BACK TO THE FUTON
– BREWED AWAKENING (coffee shop)
– CURL UP A DYE (hair salon)
– PLANET OF THE GRAPES (wine shop) 
– SPEX IN THE CITY (glasses?)
– TEQUILA MOCKINGBIRD
– WOK THIS WAY
– THE LEANING TOWER OF PIZZA
And how about the Vietnamse noodle shop, PHO SHO! In fact there are a lot of great PHO puns, including 9021PHO:
