Police said two of those wounded in the twin explosions were treated and discharged on Thursday. No arrest has been made so far.
North Eastern police boss Philip Tuimur said the explosions targeted the restaurant and the kiosk frequented by locals for food and other essentials.
He added police and other security agencies were investigating the incident.
Tuimur chaired a crisis meeting Thursday to discuss how they would tackle the increasing attacks in the area.
The explosions were the latest targeting the region in a series that have hit the country since troops crossed into Somalia in October to fight Islamist militants.
There are fears of more similar ones and police keep asking Kenyans to be vigilant.
Kenya has blamed Somalia's Al Shabaab, a movement linked to al Qaeda.
The attackers have targeted Kenya's northeast, the capital and Mombasa, threatening the country's lucrative tourism sector.
On Monday one police officer was killed and another one is nursing serious wounds following an ambush in Lagdera area, near the Somali.
The officers were on normal patrol when they were ambushed by gunmen police believe are remnants of Somalia’s Al-shabaab militants.
