I recently went to Las Vegas and ate at an unbelievably good Thai restaurant called Lotus of Siam. I was told by chowhounds ahead of time to ask for the "secret"(really not so secret anymore) northern Thai menu. This place had so many dishes I had never heard of plus all the familiar ones. Me and 2 other people had about 6 different dishes while we were there and the food surpassed any other Thai food I had ever had. In fact the meal was one of the best I have ever had.
My question is, Are there any places in town with "secret" menu's or are there any really authentic adventerous thai restaurants in town? I've been to Kanomwan, which is great but not extremely adventerous, Vungh ? on 610 N, very good as well but not crazy adventerous and many other thai places including Nit Noi and sawadee which are bland and boring.
