Restaurant recommendations within walking distance to Hilton Bonaventure
DNA is very good, but a 20 mins walk. Europea is maybe 10-15 minutes away, Toque only 10. However, all 3 restaurants are very expensive (by Mtl standards). I am mentionning them since you mentionned Pied du Cochon. Of the 3, DNA is probably the closest to what you're looking for, and the least expensive of these 3.
If you are looking for mid-priced options, Kitchen Gallery Poisson comes to mind (10 mins walk). There are more restaurants, mainly on or around McGill street...
Thanks to everyone for the recos. Ended up eating an excelllent meal at DNA - chef's tasting menu. The staff were friendly and attentive and generally knowledgable about the dishes served. A few off-menu surprises (I mean that in a good way). Good choice for solo dining - there are two somfortable bars. Chef took time to chat. A leisurely 20 minute walk back to the Hilton.
