Wells' review seems fair.
Deb and I went with another MF couple a few weeks back. I didn't write down the specific dishes we had and, as expected, my memory fails me on the specifics.
Overall the comparison to Kao Soy and Chiang Mai is a good one. Limited menu, a number of dishes not found at other Thai restaurants, and heat levels on the high side verging on the overwhelming. If your tolerance for heat is high you'll be OK although it's a bit like getting punched in the face 3 or 4 times in a row. At other Thai places you can mix and match very hot and mid range dishes. At UB they serve things the way they think they should be. If one of your dinner companions has limited tolerance for heat they better be a good sport.
I liked much of what I had - other people did too. OTOH I'd like a deeper menu. UB is fine if you're in the mood for what they have. If you're not, you need to go someplace else.
BYO for now. That keeps the prices down. The menu averages 20% to 30% higher than the Queens Thai pantheon. Then again, that's still relatively inexpensive.
In Carroll Gardens UB is definitely the flavor of the month. My friend recommended that we arrive early since they get really busy at prime time. He was right. We got there at 6:30 and got one of the last tables. People who arrived at 7:00 had to wait. I'd be more inclined to put this place in the rotation if seating wasn't a potential issue.
Winter visits could also be problematic. The place only seats about 30 people and table choice was restricted. There were a couple of tables right by the door and the people sitting there ate with their coats on.
The chef/owner was on the floor and was absolutely charming. I wish him success.
