Oumeul Somerset Mall leaves bad taste

We visited Oumeul in Somerset Mall for breakfast and waited almost an hour for our food. Upon arrival we were offered drinks which we received in a few minutes. We them ordered our food but after that got flat ignored by our waiter. We subsequently enquired about our food only to get told the gas ran out and had to be replaced. We then wanted to cancel our order but the manager was very intimidating and rude. We feel that the situation regarding the gas could have been communicated to us which we would have understood.
