Some online retailers are quick to say whether or not they'll accept Bitcoins, but local shops aren't always so forthcoming -- and community mapping efforts like CoinMap only reveal so much. It might not be hard to find a cryptocurrency-friendly store in the near future, though. Yelp has added a flag that lets business owners identify themselves as Bitcoin-friendly, making it easier to spot places that take virtual cash.
It's not a perfect solution at this stage. Some searches work, but you may occasionally have to visit a business page to confirm that it allows digital coinage. There's also no guarantee that you'll get a complete map, since locations have to both put themselves on Yelp and remember to set that flag. Even so, the addition should give you a better sense of when it's okay to leave your old-fashioned physical money at home.
