I am a Dallas transplant, originally from the Midwest.
I saw the Diners Drive-Ins and Dives spot on this place and thought, "Eh. Being on TV probably ruined whatever they had going." I can be cynical.
I have to disagree with the extremely negative reviews I've read. The atmosphere lacks high ceilings, square footage, cool light fixtures, and intense electronic music (when it's busy, it's too loud for music). At times, it is too busy, putting a larger workload on the staff. Don't expect them to be excited about it (would you be?). They might let you know if you could've been clearer about your order, or faster about it. You know what? It's actually refreshing authenticity. I don't think they've ever been outright rude to me, however. The food has been consistently very good. If it's too busy, go somewhere else - like you would at ANY restaurant. The sausage pizza is fantastic, and the crust is nice and thin. I think that this style of pizza goes better with beer. The patrons have range. You can find almost any type of person in there. What I do notice - is that you'll see a lot of people that give off the Midwestern vibe. I like the atmosphere and the people. It makes me feel like I'm somewhere near Chicago again. If the food was terrible and the staff was overly rude - I wouldn't go back. As it stands, I hope nothing changes at Louie's.
