Yup, this place does it for me.
I was in Madison for just a day visiting the infamous Corey D, and we were absolutely starving for lunch. We stopped in with only about 45 minutes to spare, and Ha Long Bay ended up being a really excellent choice! Thai heaven happening here (as well as Vietnamese and Laotian.)
First of all, the menu is huge. You're going to need a good few minutes to decide what you're going to order. For the sake of time (and because it's my absolute favorite), I quickly decided on the yellow curry lunch special with a cucumber salad on the side.
While we were waiting, there was a pair next to us that got their food extra spicy... we were coughing all the way from our table! That's really the only negative thing I have to say here... it was so, so smoky in there and my hair even smelled like curry for a while after I left. They definitely need to do something to improve ventilation! Regardless, our lunch happily went on.
My lunch was everything I wanted it to be -- the cucumber salad was excellent, and my yellow curry with chicken was perfectly spicy and full of flavor. I seriously didn't want to stop eating.
We paid our bill (which was so cheap - $16 and change for two lunch specials) and were on our way. This place is so good, and I'll be stopping in during my next visit to Madison!
