According to my Photos.app timestamps I went at 5:30PM and there were no lines at all, too.

I actually didn't came out that impressed - sure, the BBQ Pork Buns definitely lived up to their reputation and are worth the trip alone, but the rest of the menu was kind of a disappointment.

I did spend the previous week in Bangkok though, eating almost everything in sight, so my heightened expectations might have had something to do with my impressions.

Agree it's more about the individual dishes rather than the entire menu, but their prawn dumplings (har gau) are also spot on.

Photos of menu I took say that I did have them too, but I can't say they were memorable.

The only two dishes from Tim Ho Wan that I _really_ remember are BBQ Pork Buns and the steamed egg cake.

Looking at the photos now — I remember thinking toasts filled with kaya were interesting too. But none of shrimp or pork dumplings, neither any of the vermicelli or steamed rice were notable.
