They're pretty good, but I prefer Mimi's fish and chips.
The problem with Henry's is everything is too greasy for me. The fish has so much batter on it that it picks up extra grease, and overpowers the flavour of the actual fish inside. And the fries stayed in the deep fryer a minute or two too long, soaking up extra grease (although they still came out crispy, not soggy).
Also, a warning about this Henry's location. They're located in the same plaza as a Henry's camera store, so make sure you've got the right one before you park!
