what are good industries to target for google places seo?

Does anybody have any ideas for types of industry to target when cold calling business offering google places seo?

restaurants, independent hotels, estate agents

rent car companys,cafes,retreats,chiropractors,dentists,carpet cleaners,jeweler, boutiques,shuh stores ect

Target those who haven't been been beat to death ie dentists, lawyers etc.
Also keep in mind you want to bring value to those who make good $$ per new client, not yogurt shops or other cheap retail businesses typically because the increase in ROI won't pencil out for them (or you).

Think OUTside the box as usual:
Here's a couple to chew on:
financial planners
wedding services (planners/photographers etc)
cpa's

Mexican restaurants. They offer drink specials and most people like Mexican food.
