I'd hoped to give a bit more description of exactly what I had up at Lao Laan-Xang, but I can't find my menus, dammit. Suffice to say that I had two veg rice paper rolls with omelet and lots of herbs, served with a nice sweet-hot (but not cloying) dipping sauce, followed by a broth based tofu soup with chopped veggies, including cherry tomatoes and squash. The larp I had was pork (sans tripe), and it had a wonderful and complex sour, hot, and herbal flavor that combined beautifully with the perfectly cooked sticky rice. I had a Lao beer with my dinner; it was very tasty, somewhat reminiscent of Singha, but less fizzy. I finished with a great big iced coffee - also very nice, and not overly sweet. Really good service, too - informed, solicitous, and accomodating.
BTW, this place is really, really small, so if you're in Mad City, and you want to try it, go early, since there's literally no place to hang around if the place is full. As noted, they have a liquor license, and carry a well-selected variety of beers; in addition to the Asian beers, they carry a couple of different Sprecher brews, and some wines by the glass as well as bottles.
My only regret is that I didn't have a chance to go twice...
