I was there last Friday with a couple of friends. The line was long but it didn't take too long for us to get in. The only thing related to Harry Potter in this place is the name (I was a bit disappointed) but it is a nice place to hang out if you live in the area. I will go back to The Lockhart for the food. The salmon is delicious and the baked brie is just the best baked brie I've ever had! The drinks are really good too and I'm coming back for those. We had the 2 specialty shared cocktails (Befuddlement Draft and Tea for two) and they were really good! Don't waste your time waiting in line though (there are better places to be in line for on a Friday/Saturday night), come back when it's empty.
