Well done OP! How well has your business done?
Here's what I strongly suggest you do, in addition to the listing suggestions:
1. Get your own announcements on Bitcoin subreddit and update your stuff there. Do the same ann threads here (why not?). Use the same for twitter and hashtag yourself.
2. Open a profile on yelp/google/tripadvisor. Make sure you add "Bitcoin accepted" to your business info. Now anyone using these engines to find coffee will see you take bitcoin!
It is good thing that Bitcoin is starting to be seen as a currency and not as asset.
To popularize cryptocurrencies there should be more shops/caffees like this:)
I think the actual users have always seen it as such. I've never considered those who buy and hold (or worse still, those who think they've bought but are actually only owning numbers in some accounts, like those ETFs or whatever form of derivatives).
You know how to popularise Bitcoin. Not more shops and cafes, but more users using, earning, spending and asking for places like this.
