What are some gourmet and affordable accommodations in Zao Onsen where you can stay for less than 20,000 yen with breakfast and dinner included?

I'm going to Zao Onsen with a friend from college. We've been talking about enjoying a leisurely meal at a hotel after soaking in hot spring. We're looking for a hotel that offers delicious breakfast and dinner for under 20,000 yen per person. Do you have any recommendations?
