I don't always work downtown but the last two times I did I stopped by the new Aroma which opened in the PATH (close to TD centre). Both times I went I really enjoyed it.
The first time I went I ordered a small salad - although it's "small" it's actually the perfect size for lunch and full of hearty ingredients. It also comes with a piece of bread so it's enough for lunch!
The second time I went was for an afternoon cappucino and a cookie. Both were great and I found out all coffees come with a cute little chocolate!
They also have their own area set up with tables and red chairs. Both times I went i was able to find a seat but I hear it gets busy. I also notice they kick ppl out who did not buy aroma food - so i guess that helps to keep tables free too!
