Charming experience with good honest euro foods. Which they try to keep in stock and price competitively. Hot food bar amazing value for eat-in.
Huge choice of rarely-seen imported packaged products, from candies and jams to pickles, canned stews and instant dumpling and salad mix dressing. Big selections of cheese fish and meat plus huge deli and fresh sauerkraut, and some decent breads.
This is a scattershot overview and there's more, but if all you do is go for a hot German-style lunch and browse the endless goodies (surely to buy something or other) this alone a good time.
Crazy candies, Advent calendars & baked goods available at Christmas time as well, which reminds me...
