An interesting look at groceries here:
Huge bottle of water (6 liters): $2.38
Large bottles of beer (16 ounces): 52 cents each
Pepsi Light (12 ounces): 61 cents
Small bottle of Evian water (16 ounces): $2.50
Small container of instant coffee (Nestle): $7.50
Imported products are expensive in general. But groceries are really inexpensive.
Eating out is much less expensive than eating in the larger, metropolitan areas in the States, like NYC or Chicago. Dinner here in Kiev, for example: A whole pizza; salad of tomato, basil and fresh mozzarella cheese, 1 large beer, 1 glass of pinot grigio and 2 cappucinos...$35. Drinks are very inexpensive, compared to in the States. Maybe that is why many, many people drink beer with meals (?). You can also find meals for much less than this example.
The news is good on this front. There are plenty of great options for food in Kiev...and the price is right :)! Be patient and adventurous with your food choices. You will find foods you enjoy here!
