I fell in love with Lotus of Siam on previous visits to Las Vegas.  In fact I have given up Thai restaurants in the San Francisco area, since they rarely compare.  Sunday lunch brought me to a \"closed\" sign at Lotus.  Luckily I used Yelp to find another Thai restaurant.  I was amazed that Komol was so close to Lotus, pleasantly surprised that it was open, and ecstactic with the quality of the food and friendly service.  This is an excellent choice for vegetarians (60% of their business is the vegetarian dishes).  I immensely enjoyed the pork panang, and look forward to sampling the fish dishes on future and frequent visits.  I agree with the comments on the spice level; use caution, especially on an initial visit.\n\nMy only complaint is that Las Vegas has two excellent Thai restaurants within a hundred yards of each other, when I cannot find comparable Thai food within a hundred miles of my home.
