I eat at Loving Hut every time I come back to HK and in fact just ate there a couple of nights ago. I agree with the previous reviewer that Loving Hut has a buzz that I had never felt before. It was really busy, and there was even free entertainment - a local lady singing English and Cantonese songs.
The menu hasn't changed since my last visit 10 months ago. Pretty extensive menu. I've always enjoyed their food. Only suggestion for improvement would be to add more fresh veggies to the set menu, which consists mostly of rice and noodle plates that are tasty but high on mock meats and veggie juliennes but low on real chunks of veggies. For that you have to look harder on the left side of the menu - the a la carte side, where you can add HK$10 to get rice and soup.
I really like their vegan cream cake. No idea how healthy it is, but they are super delicious and give me hope that I can easily transition from a vegetarian to vegan diet. (I've been vegetarian since the early 80's and would have been vegan years ago if not for my fondness for dessert!)
I like to eat at Loving Hut wherever I travel globally, as the menus are all locally-based. Not sure how good or bad their cult leader is... a concern for this devout atheist :) but hopefully I can continue eating there!
