First time I went to Hiltl I loaded up the plate. Went to get it weighed. And the 45 Francer (45 USD) as I call it was up. It’s not the cheapest, but the buffet food is consistently good. And in my time in Zurich they have expanded rapidly (recently Bahnhofstrasse and Landstrasse). And I like the free water. Just watch you don’t load the plate too heavily!
