My friend introduced this restaurant to me when I was craving udon. I had the "handmade udon with vegetables" in "handmade spicy tomato soup" (HK$66). The udon was nice and chewy and the soup was decent. I'm really picky about soups, more so since I became vegetarian but this I liked.
An OK price for the flavour. If you're gonna eat at Dai Mon Yokocho 大門橫丁 in Mong Kok, it's a green light from me, even vegetarians will be happy.
