I stopped in for a quick beer or two and a couple of "tapas". It was an enjoyable experience. The place is quite lovely with exposed limestone and I found the staff attentive and very pleasant. I ordered the croquettes and the octopus, which were both delicious and delivered promptly. The Estrella beer had just arrived and was a pleasant reminder of my summers spent in Spain.
The counterbalance is that if you're looking for a truly Spanish restaurant or a genuine tapas bar, this place is neither at the moment. Their Spanish wine selection is quite small, the limited menu is "inspired by" but not truly Spanish, and they incorrectly seem to think (as most Canadian "tapas bars" do) that a tapa is a share plate versus a small individual dish hence the nearly $40 for two 'tapas', two beer and a tip. (these are my opinions only based on having lived in Madrid and visiting Spain every summer for years). Still, Barsa is a positive addition to the east side and I look forward to when their patio opens.
