About as authentic as it gets.
A dozen cheddar perogies, fried in oil & onion as they should be, ring in at $4.25. Nice portion of filling and the dough is properly thin. Appropriately served with a side of sour cream.
We also indulged in a cabbage roll (I believe that is also around $4), which was massive and filled to the brim. I grabbed a piece and the sauce tasted spot on with its flavour (tomato-based). I also ordered a small Russian potato salad, and again, the flavours were there with the familiar friends of peas, carrots, etc. We had a filling lunch for two come in around $17 with a shared pop.
It's a no frills place, with your food heated up in the microwave. We ordered on and on, and the young man working apologized for not timing it properly - not his fault, as we kept adding and adding to our order.
Do yourself a favour and drop into this place. They even have trays of items for takeout so you can indulge at home. Their products are clearly homemade and not imported in from one of the big factories.
