The "Other" Vientiane .....
The other Vientiane is waaaaayyyyyy better than the Vientiane near the University. The only reason to frequent the other place is proximity to the university. This Vientiane has: better food. Friendlier service. Onions will not constitute 50% of your meal. It's clean. You will not need immediate access to the bathroom after eating here. It is also spicer - under no circumstances should you attempt 4 stars. Consider yourself warned.
I've been here many, many times in my time in Madison. The best dish by far is the curry squash.... Also good is the ginger strip dish, the spring rolls, and the Singapore noodles...
