I visited Bar Louie for happy hour on a Tuesday, and granted, it's a Tuesday, but there was definitely a ghost town feel to the place, given how large it is, and only perhaps 6 patrons. At the same time on a Tuesday, I'd expect 30 or more at Smokin' Joes for instance. The Tuesday $1 burger special sounded good, but the burger was disappointing, flavorless and dry, and took surprisingly long to arrive given how empty the place was. The bar staff were nice enough, but seemed (understandably) bored. The place is clean and well-kept but has an industrial chain kind of feeling to it, not the sort of bar charm you'll find in so many other Pittsburgh establishments; no warmth.
