Thank you, but I am from Geneva, as implied in the title of this post. Those shops are in the German part of Switzerland. I'm from the French part and don't wish to venture out into krautland just for a packet of pierogi or paluszki.
I'll check out the food section in Globus for sure, thanks for the tip. I'm looking for Polish/Ukrainian stuff in general. Makowiec, kasza gryczana and ser bialy are things I'm unable to find in regular shops.
I've heard 'rumours' of a great shop near the Russian consulate in Geneva which stocks russian, polish and romanian stuff.
I've also found this shop, but the website puts me off.
By the way "La Perla" is quite close to "Food City" Plainpalais. The advantage of Pam in Meyran is significantly lower prices, but the product range is also smaller.
There is a Russian food shop Katousha next to Russian Consulate. Also in Plainpalais in front of Unimail and UBS. There is a huge shop at the corner selling magazines, cigarettes, etc. They have a wide choice of Russian, Ukrainian, Bulgarian food. Open daily and very late. It is at the crossroad.
