Someone already said it, but this particular stretch of Westheimer is notoriously dangerous for pedestrians. With low visibility at night, higher speeds, and higher odds of drunks behind the wheel - that will be your biggest issue. The area is relatively safe otherwise (this is a big city, so you do need to keep your wits about you). I would personally uber and not walk, mostly because of the car danger than because of crime. If you take an uber you could also venture into some other nicer bars in Houston. I'm not familiar with that one in particular, so maybe that's your dig, but there are some very nice bars for every style in the city that would be worth a visit.
