USSR, this chart takes some figuring, but is worth your while in terms of getting a sense of Soviet availability.
The table is titled "Consumption of the main food goods in the US and Russia (per capita average, in kilograms):
The top part with the dates shows USA 1989, RSFSR (the Russian republic in the USSR) 1989, USA 1997, Russia 1997, USA 2003, Russia 2004, USA 2009, Russia 2010
The products on the left are listed as (in order): Meat and meat products, Milk and milk products, Eggs (individual eggs) Fish and fish products, Sugar, Bread products, and Potatoes.
In today's Russia, there are no shortages of food products like there often were in the Soviet period; the stores are packed with stuff like any Western supermarket. But paradoxically, Russian consumption of many goods has declined very significantly.
If you need the source, it's from Russian sociologist Sergei Kara Murza's thorough tom
White Book on Russia. The book has several editions, and can be found here.
http://www.kara-murza.ru/books/wb/I'd like to add a few things:
* Soviet products, as Comrade Gulper said, were of very high quality, especially compared with what is being sold in Russia today. There are entire forum communities now filled with nostalgia about Soviet sausages or cheeses, complete with regular requests of 'where can I find these items made according to Soviet standards?' The answer, typically, is 'Belarus'.
* With a few rare exceptions, the shortages regularly talked about as dogma in many Western resources of even basic things like bread, root vegetables, milk, etc. only existed beginning in the late 1980s and early 1990s, when the country's supply system was destroyed and the country was on the verge of collapse. It was
not a regular occurrence, even in the 'stagnation years'.
* In certain areas, shortages of many goods did exist; for instance, the much discussed 'sausage trains' of popular lore (with people commuting or traveling to areas were supplies were plentiful to stock up and return home) were real, particularly from the 1970s on.
* Certain goods, in certain seasons, were simply unavailable in many parts of the country. For instance, finding locally sold bananas or fresh leafy greens in many parts of Siberia was simply impossible during winter. This had to do with several factors, including a) the lack of technology to preserve the food on its way to the store b) lack of storage facilities and c) lack of local greenhouses (with the exception of some regions, including Ligachev's Tomsk region) where delicate vegetables could be grown even in winter.
* When taking account of people's consumption, one factor Western statisticians long failed to considered was 'obshepit' - 'public catering', that is food which was provided in schools, in work cafeterias, from street kiosks, in barracks, hospitals and nursing homes. In other words, judging strictly by store shelves is not an effective way to measure consumption. This was a point recently brought up by Kara-Murza actually.
* About classy restaurants and the fancy meals they served, they certainly existed, but were rather rare, and very uppity; first off, it was hard to get in. Often a rude doorman or babushka would simply shush you away or tell you there are no places if you weren't dressed the part or looked like a foreigner. Second, the waiters were usually rude, since they, not the customer, were effectively kings. Third, again, if the waiters felt you weren't up to snuff, they could simply not serve you some menu items, suggesting they were out of stock or making up some other lie. In general, from everything I've read and heard from family and friends, it was all a pretty unpleasant experience.
