It's worth asking the hotel staff for recommendations, but always take the answer with a grain of salt. No matter how carefully your explain what you want, it's still possible you'll find yourself at a restaurant that the staff member enjoys, not what you enjoy. And no matter how shrewdly you word your question or how genuine the staff seem in their recommendation, you may find yourself in a place they recommend only because they get a kickback. So go ahead and ask, but pair the recommendation with what you've learned via your own research.
