Sorry to bump up an old post, but I couldn't find anything more recent on the topic of LTH (perhaps we should call it just Three Happiness now, as the larger Three Happiness is now a stretch of the redirected Wentworth Ave?)
I think this place still fires on all cylinders, and is my general go-to in Chinatown. I think the much-lauded shell-on salt and pepper shrimp is one of the greatest dishes I've had the pleasure to enjoy. Many of my closest friends and family have been turned on to the sheer greatness of their peanut-y egg rolls as well (many have also become addicted!)
Anyways, not just here to gush (although I could do that for a while). I wanted to post their updated pandemic hours, as I was just down there and had trouble this time as well as a previous occasion in reaching them in the slightly-before-lunch hours. Here's the picture I just snapped as I was walking Chinatown (edit: couldn't get the images to work, you'll have to trust me)
Sunday-Thursday: 12pm-12am
Friday-Saturday: 12pm-1am
They also may not open
exactly at 12, they're not quite that kind of business.
