Andrum is a centrally-located, 100% vegetarian restaurant in downtown Gothenburg. It's small but…read morehouses an equally as intimate and quiet atmosphere, if you come at the proper time. Come during the lunch rush, however, and it will likely be packed.
Diners can choose from various entries or eat from the buffet, which (as I've been told) is relatively the same from day-to-day. What the actual foods are is a bit unclear if you don't speak Swedish, but nothing I had was bad. And everything in the restaurant is clearly labeled as to whether or not it's vegan, which is a huge plus.
The pricing is acceptable (79 SEK, or $12, for the buffet) for Swedish standards. It's not a place I'd frequent on a regular basis, but it's worth going back to more than once. My meal was unique, tasty, and filling.
