The other blast happened at a bar near a hotel in the Nyali beach area. There are no reports of casualties there.
Kenya has been hit by a spate of attacks blamed by the government on Somali Islamist militants.
The al-Qaeda-linked group al-Shabab has carried out several attacks in Kenya since 2011, when Kenya sent troops into Somalia to battle it.
