I am 100% Chinese, so I am qualified to review this place as the Most Authentic hot pot restaurant in town. All the food here are up to the standard of authentic, like those I taste in China, not mentioned fresh and clean. All the other restaurants in town offer hot pot could not provide food up to this standard.
Based on my personal experiences, I like the tomato soup base. It brings up the flavor in vegetables. Bonus points for the soup tastes after cooking all the meat in there. Hot pot sausage is another dish you must try. The mini eggs taste incredible juicy after cooking in the broth and the egg yolk is very tasteful. I don't eat lamb personally but my friends like it a lot.
For the dinning environment, I would say it is good for family, nice for a date and fun for group hang outs. It totally worths for the money you pay for. Servers here are very nice and the manager keep checking on us make sure we had a good time.
Anyway, I would say Hot Pot Lab is a fun experience. It would be a good place to treat yourself. :)
