Turning the laws of economics on their collective heads, there are two fantastic Nepalese establishments mere feet from each other in Madison.
While there is some connection between the two (I believe the same family owns both) and they both serve tasty and comforting food, the slight differences are noticeable. Chautara clearly provides a higher end dining experience. Less crowding, better wait service, more pleasant views. However, folks with more respectable palates than mine claim the food at Himlu Chuli is more flavorful. Perhaps a higher level of delicious that I can't quite discern.
In any case, they're both worth a visit.
