If you don't have plans for tomorrow night, Halloween, I have a solid recommendation for you - Waller Creek Pub.
About 2 blocks from Franklin BBQ, this is a great place to enjoy your nice a spookiness. For the fifth year in a row, Waller is throwing its annual “Grand Opening”, with Halloween cocktails, karaoke, rare beers and prizes for the craziest costumes.
The bartenders are always friendly and helpful when choosing drinks. The bar are is relaxing and they also have other sections to just hang with your friends. Very chill, relaxing spot with awesome staff. The music being played was outstanding both times I visited.
My personal recommendation - Get their Reuben and Asian fries and accompany it with a beer from their respectable beer list.
Best of all - no cost to enter.
Try to beat that, you ghosts and goblins!
