Is it acceptable to ask which schools teach a specific style in a certain area, or is that too localized?
e.g. "What Wing Chun schools are there in Yorkshire, UK?" or "Recommendations for Hapkido schools in Los Angeles?"
I think it's too localized. You could just as well do a search of local business listings and be done with it. Businesses may not stick around forever. New ones might pop up, or they might change locations which means that answers will also change over time.
Also, the SE Q&A model isn't good for "recommendations" and those questions are likely to be closed as "Not Constructive." Those questions will solicit opinions, and there are plenty other websites that can provide that for you.
