As a hungry couple, we tried to find a decent restaurant to eat at 10 pm near to Leonardo Royal Hotel in Frankfurt. This one was just 400m walking from the hotel (and the weather was chilly). House wine was ok, service was a little less than expected (spanish service), it took a while to bring us the menues, but the food was also very good. We had pork tenderloin and beef steak with salads instead of house specialities, since we were not particularly fans of spanish cuisine and beverages. I saved the place for further visits, in case we will be there again.
