There is a free bus from Rechnoy Vokzal that runs every half hour or hour. However, it can be a bit difficult to find at first. There are also marshrutka leaving every few minutes that cost around 30 rubles (one dollar) that pass the mall. They say Auchan (ашан) on front. It takes about five minutes by marshrutka. Once at the mall, it is easy to find the schedule for the shuttle buses back to the subway.
There is a location in the food court and also a sit down restaurant. I recommend the sit down restaurant, as the stuff in the food court is prepared in advance and they didn't seem to be very busy when I was there, so the food was sitting around for a long time. On the menu in the restaurant, I saw on the menu a veggie burger and at first I wanted to order that, but they told me they did not have it. So I had a seitan dish which was good. However, after eating there, I realized there was also a location in the food court, and there they had veggie burgers, but they did not tell me that when I was asking about the veggie burgers. But perhaps it's just as well because the food in the food court appeared to have been sitting around for a while. There was no lunch set when I was there but during the week, before five I believe, there is a discount on the regular menu. I visited the restaurant last year so things may have changed since then.
