another regular haunt for me and another place with a nice but smallish outdoor area,Kozel pub, good food and great beer,service can be a hit or a miss but I have always found it good

huge place with various bars and food is pretty good,tank pilsner urquell.big outdoor area,my only complaint is that you have to ask for the key for the toilets.

the bar of the Staropramen brewery,there is actually 2 places next door to each other , one is just the bar the other the restaurant,you can try the whole range of Staropramen beers, food is good and service excellent,can get busy though.

you have to go through an little alley to get to this place but great place,about 12 beers on tap from all over the Czech republic,food is pretty decent and service good.
these are all places I have been in several times most of them in the last year and can recommend them highly.

this is a new micro brewery that I have not been to before,I have a friend that works in the Andel area and going to meet him there for lunch in a couple of weeks time.
Hope this helps, but as I have said there really are numerous places to try in the area,so try a few and let us know how you get on.
Andel is a great Tram /metro hub so easy to get to lots of places from there.
