Hubby and I went here, following the other Happy Cow recommendations; perhaps we just went on a bad day but there was no hot dish - it was being created but we were too early ( it was 14:00......) so we each had a salad. Yes, it was cheap but so uninspiring. Yellow rocket leaves, plain boiled pasta, dried out kidney beans, no dressing or offer of same. If you like smoke, black walls and skulls, dirty cutlery and glasses and eating in a space that feels like you are intruding on something illicit, then you will be OK. As a life veggie, in my 50s, I was not comfortable and would not recommend. There are more suitable places for a vegetarian to eat in Oslo. Sorry Blitz, but you disappointed me.
Cons: Smoke., Somewhat intimidating atmosphere.
