There are a lot of bakeries in Lesliville. They ALL make cupcakes.
Altitude makes savory pies, samosas and big cupcakes. They are almost double the size of Sweet Bliss... but they aren't as good.
Their prices are standard/fair and everything is O-K. I don't find the staff particularly friendly, and I have been there twice and spoken with 2 different people. I always get the feeling that they want me to leave.
A high point is the Sour Cream Apple Crumble Tart, which is very good - and they always have them. They also have pretty reasonable hours for the area, and I have been disappointed in the past by Sweet Bliss being closed at random times I think they should be open.
In summary, I think Sweet Bliss is better (and it's right up the street) but Altitude is OK and has 'different' stuff (like savory pies).
