I very much doubt you'd call someone 'stupid' in the street, pub, anywhere expect online.
Could you perhaps point out where I call anybody in this thread stupid? polkamaniac has clearly never eaten in the restaurants in the photo: he describes them as "street restaurants" and anybody who has been to Warsaw will recognise that those restaurants are very definitely not street restaurants, they are restaurants in the old town square which have tables in the square during summer.
polkamaniac seems to specialise in reproducing restaurant 'reviews' from a particular website: warsaw-life.com. How strange.
You really should learn some basic online manners.
You really should learn some basic reading comprehension skills.
The Old Town is considered a tourist trap, with vastly inflated prices, and best avoided.
No wonder your guide is so tragic! There are a number of cracking places in the Old Town which offer quality food at below average prices. I can think of four within two minutes for the market square (plus two more in the New Town), one of which is the best restaurant of its type in all of Poland. None of them are on the market square. Good to see that your guide is in the hands of somebody who knows Warsaw so well.
