Yes, it is nice when a business welcomes cyclists. A while back, I was locking up my bike outside a restaurant. The manager came outside and asked me to bring the bike inside the restaurant. So, he will be getting more of my business, even though there are many restaurants closer to me.
And, some places do the opposite. Make clear that don't want bikes around. When that happens, I make a point of telling the manager he has lost all of my business. And lost the business of every cyclist I talk with.
