Oregano's is nothing special. It sounds really harsh, but restaurants like Oregano's are a dime a dozen. Think an Italian-style Chili's, take out the Italian, substitute Chicago-style crust and small novel inventions in obese-size portions and you'll arrive at Oregano's.
I've been twice and both times I was unimpressed. The food was mostly a sad melding of American-Italian food, introducing the worst parts of both. The sandwich I had was drowned in tomato sauce and even the salads were gigantor.
The decor reminds me of an Applebee's -- and most certainly not in a good way. I'm honestly at a loss for what to say next. Unless I have my arm twisted, I'm not going to be returning here.
