The Duang Champa rest. (& guest house) has changed its name to Aspara (www.theaspura.com).
Ate twice at the 3 elephant cafe on the main street towards the west end of town. Lightly battered stuffed bamboo shoots with a slightly sweet sauce, finely-textured sausage, and a chicken stew with fungus, buffalo skin, local greens, lemon grass, and not overcooked green beans all in a good stock, plus an iced coffee and a big beer = $6.50. I love this town! For the second meal we had spring rolls, which were small and somewhat doughy because that is what happens when you use less filling with the same-sized wrapper, and an excellent fermented fish stew (#2 on the main dish menu)
On the Nam Khan river side of the peninsula near the confluence with the Mekong was a rest. where a lot of locals were eating lunch. Was told that it was a duck rest. Wish that I had not just eaten lunch.
The best meal we had in LP was at the Boungnasouk Guesthouse & Rest. on the road along the Mekong. The chicken stew had chunks of wood and other vegetable matter that gave it a more complex taste, though it was cheaper, than the 3 e. c. stews.
My general advice for LP dining is if it reads well on the menu and the price is O.K., try it. What the hell.
