Recommendation: Well braised pork intestine, fresher oyster and cleaner.
For those that detest the dusty and grimeyy nightmarkets, but still want to taste Taiwanese snackfoods can go to Lucky Horse. All of their items are under 100 NT and only 5 or 10 NT more than the nightmarket price for similar foods. Their signature dish is the oyster/pork intestine string noodles, and it goes for 45 NT for a small and 60 for big. They also offer wild boar sausages for 35 NT, or you can get the combo for 89 NT which comes with a drink. They have a clean interior, plenty of seating, and a professional looking service staff.
I ordered a small bowl of oyster/pork intestine string noodles and found it to be pretty good. The noodles are not as Q, but the ingredients were very savory. The pork intestine were braised well, and carried it's own distinct flavor while not tasting dirty. The oysters were not covered in too much yam starch in its precooking stage, so it did not have an extra gooey consistency. The soup itself was on the heavier side, which is to my liking. Not heavy with vinegar, but with this soy saucey, braised flavor. This bowl beats a lot of other stalls in the Gong Guan area, but it still can not top #1 because of their lack of quality noodles.
