only real advice is that booze in bars aint cheap - youre lookin at £3+ a pint (not gonna kill ya but its not a bargain either)
However find yourself an ALbert Heijn (Tesco to you and me!) and ut a crate of grolsch for about a fiver, get plastered, THEN go out!
You can read up loads on the Dam ont he web, but if youre there a few dyas and want to get out and about get on a train to Zandvoort which is their version of Scarborough. Could spend a few hours ont he beach there and in the bars and old town for summat different.
Also try "Friet Speciaal mit Frikandel Speciaal". Thats spicy sausage and chips with mayonnaise, curry sauce and diced raw onion. SOunds awful, tastes the business! You will put about 4 stone on though!
