Roberts is the contracted restaurant to serve food to the day trippers that come on the coaches from Puerto Princessa to see the underground river, we were staying in Sabang for a few nights at the Green Verde (excellent) so went to Roberts for an evening meal. They have absolutely no interest in serving food to anyone in the evening despite being open. The young girl served with an attitude and when I asked what an item on the menu was she said 'I don't know, I'm not the cook!' The food was practically thrown at us and was awful (even more so we discovered the next morning!) There was no level of service, they were clearly not interested.
