Bump worked - I saw it! WPE will close at the same time as the other restaurants as DTD Marketplace. (same time every weeknight and a little later on Fridays and Saturdays, which is around 11 or 11.30 pm I think on the weekends and around 11.00 pm on the other days). There is a brochure where it is printed - can't seem to find the one right now, but I think it may be on the back of the DTD map(?) I can't say if they will be open when you come out though as I have never been to House of Blues for a gig at night and I don't know how late you are likely to be. If you have your heart set on WPE afterwards it may be worth popping in and confirming what time they close that night before you go to HoB and if need be, keep an eye on your time.
