My partner and I went here for dinner - I recommend you book on a weekend night as they get quite busy - you can book via the website which is handy :)
When we arrived we stood at the counter for quite a long time while two staff members spoke to each other for about 10-15 minutes - they saw us and continued with their conversation. After they finished one of the staff members took us to our table.
My partner and I ordered a salad each as a starter - I chose the fig, cherry tomato salad with hazelnut dressing. When it came out it was a garden salad and had quite a few things it didn't mention on the menu - carrot, sprouts, normal tomatoes (no cherry tomatoes) - no figs, didn't look like any dressing. I asked the waitress and she got a menu and pointed to the one I ordered saying that is what I had. I told her yes that is the one I ordered but is not this one - it has quite a few different things in it not mentioned on the menu and the two main ingredients figs & cherry tomatoes were not in it. She said she would take it back to the kitchen - she returned with the same salad just topped with some cherry tomatoes and figs. I am pretty sure they got my order wrong and then didn't want to make another salad - it was quite bland and definitely no dressing.
I asked which of their wines were vegan and none of the staff could tell me. They didn't even bother to try to find out. So strange for a vegetarian restaurant - you should really know all your products are sustainable - some wines aren't even vegetarian (fish products) - and they didn't even know that! I was not impressed.
For main I ordered the raw lasagne - it was really tasty but had a lot of cashew cheese - would have been good to have a bit more zucchini to make it a bit lighter, but it was quite delicious :) My partner ordered empanadas (not vegan) and he said they were really good. I also ordered a fresh juice which was pretty good.
Service was quite slow at times - particularly near the start of our meal and the restaurant wasn't busy until much later so wasn't sure why service was so slow?
Overall not a bad meal, the salads could definitely use some flavour and good dressing - my partner's salad was quite bland too. Also staff could be a bit more attentive.
Not sure I would go back - there are plenty of veg restaurants in Barcelona that I would probably rather go to. Not a completely bad experience though.
Cons: Staff don't know of vegan wine, Slow service and inattentive staff, Bland salad
