Muang Ngoi’s Riverside Restaurant is Lonely Planet’s top pick ( probably rightly so) for eating in Muang Ngoi, particularly for it’s great river views.
The Chicken Laap is the standout dish and the coffee is great and the mango lassi also very good and there’s a well stocked bar.
Pumpkin curries with fish or chicken and the fish with lemon is OK.
The Suzy and Spring Rolls are also OK…
…and the Chicken Marsala and Orlam are just OK.
As you go up the path from the boat look for the signs on the right.
It’s a wooden building jutting out across the river, at the far right in the photo below.
