>They serve them with a sweet thai chili sauce, but they didn't include the recipe for that, dunno why.
Try this:

Thai dipping sauce

1 tsp. red pepper flakes
3 small garlic cloves, minced or pressed
1/4 cup distilled white vinegar
1/4 cup juice from 2-3 limes
2 tblsp. fish sauce
1/3 cup sugar

Whisk ingredients in small bowl until sugar dissolves. Let stand 1
hour at room temp. to allow flavors to meld.
