milk bars but that's not quite the same thing.
There's the new generation of milk bars (a logical evolution) and there's also so ethical g else that you see in a few places. Sort of two-in-one or three-in-one places. One kitchen and a milk bar and one or two better places all adjacent. I used to live near one. The prices and appearance differed; milk bars have a subsidy and in Warsaw they usually accept food stamps, there was one with high tables, cheap set meals and beer next to it where people often just went for a drink, and there was a third with tablecloths and waitresses.
Restauracja Stylowa in Nowa Huta once.
There are a few nice ones there, good atmosphere and very traditional.
I've heard of them. There's none in my area though
Hopefully they'll open one. They really are good.
