I'll keep this short.
1. It's cheap. No other bar I have been to in Amsterdam is this cheap, €5 ish for a round is very good.
2. Snacks are very nice and again reasonably priced. Oosterwurst (smoked beef sausage) was very meaty, almost steak tartare!
3. The beer is excellent, we tried every single one and they are all good.
4. The bar itself is nice. I particularly enjoy the way the sterile nature of the brewers art has spilled into the bar - meaning it is extremely ergonomic.
People who say it is 'far' from the centre... It's a mile, that's not really far to walk unless you are very young/very old. If so get a tram!
