Go an eat in the top(ish) floor of the MBK mall where the locals eat
Agreed, I had no idea what to eat so followed a guy around and copied everything he had, it worked out great.
Scooters on Koh Lanta are a good idea, the roads are a little more chilled and its very nice to have the freedom to explore.
I was on Koh Lanta in the off season and still loved it, after 5 weeks of excess on Samui/phangan/phiphi a little quiet time was much appreciated!
Enjoy it, Im jealous.
