Yes, in fact diners are the highest converters, I've run numerous offers through those placemats with great responses on most. Affiliate marketing, work from home, even some dating sites. Most advertisers don't even know this method exists.
Ive tried it as well once. I hosted a local online tournament for students in a city and went to some small restaurants and bought ad space on each table where I promoted this tournament.
It was a success! I hit the targetgroup really well and got lots of new RMPs.
I guess it all comes down to what type of restaurant youre placing our ads on.
