I don't recall seeing a bar but there is a separate building that serves lunch and dinner. We only had breakfast. The public baths are separate ones for men and women. You do not have to reserve - just go. Open til 11 pm, women's sauna turned off at 9 pm. Really welcomed it after sightseeing all day in December. Front desk staff is very helpful and I am sure you can ask them if you have questions about how to use the Japanese bath. It is big- many people can be there at one time. I also recommend the gift shop, which has lots of really nice products from the Kyoto area. This saves time when you want to shop before leaving.
