Tried out Vientiane for lunch...many menu options, reasonable prices, and huge portions. They had about five lunch specials that were only $6-7.
We tried the Pad Thai with tofu, which was pretty good. We also had the daily curry special with tofu, which was very tasty. The spring rolls were ok...nothing to write home about.
Service is definitely not their strong point. Don't expect a cheery greeting when you walk in. After waiting for the check for about 10 minutes, we finally realized that your bill is waiting for you at the counter, where you pay and ask for take-out boxes. Overall, decent thai food.
