I love macarons, but rarely visit By Ollia because of parking! Made it here the other day and picked up a 7-flavour box for 14$ which seems to be the standard rate for macarons in Calgary these days. The flavour assortment was good, and I picked up one savoury macaron (maple bacon) out of curiousity as my 'bonus' 7th macaron - the sensation was a bit odd but the bacon flavour definitely came through! Their iced teas are also very good, though I wish they used a filter to poor as I had a lot of loose leaf bits in my tea at the bottom, which weren't as pleasant to drink!
The store decor is beautiful and the staff are so helpful. I'll definitely be back... when parking permits!
