Moscow qualifier.

How should we organize the gathering: will everyone bring something, or will someone take on the responsibility, and the rest will chip in?

It's simple; they have a decent kitchen, the prices are reasonable, and they also have a selection of weak alcoholic beverages (a can of beer costs 50 rubles). I can bring my own strong drinks (meaning we can go to the store and buy whatever we decide on; it's nearby). We'll get everything else there.
