My family and I went here during a visit to Montreal. I had to try 3 different times to make a reservation - if you're interested, try calling 2-3 weeks in advance (kinda made me feel like a rockstar to just walk right in though, not gonna lie). I'd advise going for a prie-fixe menu or sticking to a certain number of tapas: it is VERY pricey here and your bill can climb quickly (I think for four people, my dad dropped over $400).
Beyond that, though, some of the most delicious and creative tapas I've ever had. Very original pairings and an extensive wine list. I'd agree that this is a place for foodies, but as a fairly adventurous eater with no particular dislikes, I was very happy here. The walls are also covered with original artwork (on discreet sale) and the rest of the decor is tasteful and makes good use of the space.
