I had read about this place on happycow and stopped in for lunch, October 2012. Here's my Loving Hut Sunset review.
It's a deep space with plenty of seating. At the front of the restaurant is a counter with glass case display of some cooked dishes (for their lunch specials - rice + one entree) and another display of colorful cakes and other snacks. Overall it's very relaxed.
The menu is extensive and most dishes come with a photo image so you can see what you might like to get. I always like to get the pho noodle soup, so I did. It arrive piping hot with a aromatic cinnamon scent. Taste was all right. I also ordered a side of potstickers (pan fried dumplings), and that was tasty, too.
The prices are inexpensive, and the food is fresh and all vegan. Our waiter was very friendly and courteous.
A good stop to get a quick bite when in the Sunset area of San Francisco.
