3.5 stars....a very reliable and reasonably priced for the financial district. I have had the naan flatbreads (tandoori is my fave but the mushroom/bacon one is tasty also), fries, and the salads (the salmon one is my fave) - all were excellent and good for sharing. The food won't knock your socks off / not fancy but it is consistently good.
There is a small patio in front (on King street). Inside, there is a bar area with some TVs. I'm not a fan of the interior (I find it dark) but I like how the resto has an overall casual/relaxed atmosphere and you can have a convo without having to yell/raise your voice. Service can be slow (ask for the cheque early if you are in a rush).
I would recommend if you are in the neighborhood and looking for a good casual meal/drink. While the patio at the beer bistro is better, I prefer the food and causal environment at O Resto.
