I've eaten at Yum Yum four times in the last 6 months and haven't had any problems with the service. The food has been fantastic on all occasions.

Just don't bother with Yum Yum unless you have at least two hours to kill! the service was dreadful! It seems they were more worried about cleaning tables or chatting on the phone than looking after diners. The food was okay but stay away from the basic dessert menu unless you like frozen ice cream! All I can say in summing up is to stay away from Yum Yum at all costs!
