Since Ubol's has come up here I've been twice. They've redecorated, sponge-painted the walls yellow, and it really is as charming as ever, moreso even. On top of this, the waitstaff are genuinely warm people who give off terrific energy. They seem eager to share their cuisine.
I have to start with dessert. The Sweet sticky rice and cocunut milk with mango is the best thing in the world. This is not a dessert I know very well, so I can't compare to the execution at other Thai places, except to state quite firmly that there's no better dessert anywhere period. The wonderful chewy texture of sticky rice combines with a light cocunuty syrup that is sweet and ever so slightly salty. Served warm, with a whole beautiful mango, this is paradise, a dish I genuinely don't want to end. Since the first time I had it I'd been fantasizing about it often, and it completely lived up to my delicious memory.
Otherwise the food has been good. We've not gone during peak hours, heeding the advice of another chowhound. We've had the Steamed Mussels appetizer, which is served in a delicious lemony broth and accompanied by a sensational Thai hot sauce. I wish there had been a few more mussels, but this was still a nice start.
The tofu jungle curry is a delicious dish. The Jungle Curry is not earth shatteringly spicy (but they'll bring you another wonderful Thai chili sauce, explosive with heat and flavor) but it is surprisingly delicate. They prepare tofu extremely well, and it comes firm, dry, and perfectly sauteed.
Noodle dishes Lard Nah and Pad See-iew have been delicious, if rather similar to Chinese chow fun.
Sometimes the shrimp tastes fresh, but not as fresh as could be imagined, if that makes sense. As a fish eating vegetarian, I'm usually most happy here with the purely vegetarian dishes - although as you can see from the above, I don't always stick to those.
I do have the sense that this place has improved since when I tried it several times a year ago, upon first moving to my current diggs - one block away. If you still remain skeptical, or are completely wedded to Sripraphai (which does seem better to me, but less nearby), go just for the dessert which is KILLER!
