I've heard so much about this place that I had pretty high expectations.
Now that I've tried it, I'm quite disappointed, and I think that the fanfare is there because it has a legacy and tradition rather than quality. I hate to break it to you, it's nothing special. The meals are sloppy, with a heap of greasy fries filling the plate. Yes, you leave full, but it's because of bread and fries. The meat dishes are average. And way overpriced. The salad is as basic as you can get. It feels like a fast food restaurant with airport pricing.
In short: average, expensive and sloppy.
