Highlands is a favorite of my family, but we've never tried Hot and Hot, so I can't compare them for you. If you want to try a place that is on par food wise but (i think) may be a little less expensive, you might consider looking at Veranda on Highland (I'm not 100% sure on it being cheaper). I liked the atmosphere there a lot, and we got to talk to the chef a couple of times as he wandered around, which I like.
