Tried this place out after reading an article on Thrillist about the 10 best Chinatown restaurants:
http://www.thrillist.com/eat/las-vegas/best-chinatown-restaurants-in-vegas
I ordered their bestselling sautéed spiced lamb, and it was just average good. It was very spicy, so they definitely got their Szechuan on, but I was a little disappointed with the portion. It felt like a lunch-sized portion, but I paid the full dinner price. Oh, and the rice was extra - really?
I would have to say that I agreed with most of the articles picks for best Chinatown eateries, at least the ones I have been to. J&Js was my first attempt at the ones I have not tried, and I am already disappointed.
Not only do I think J&Js is not the best Szechuan in Chinatown, but its bestselling sautéed spiced lamb is not even the best Szechuan spiced lamb dish in Chinatown (that honor has to go to Yunnan Garden).
I sure hope the rest of the list is not as far off.
