Given the portions, I think this place is a little cheaper than Dolce which is just meters away on College Street. Its kind of hard to tell because the way a server adds to the top can make a difference, but I think you get a little more here.
I can't see a difference in flavour offerings between Creme and Dolce, but I can tell you this, Dolce is so packed you bump into people and can hardly find a seat, but at Creme, their lack of marketing means you can sit where you want, and have some peace.
If someone at your table is big into cakes or chocolates, Creme might be better as it has a big selection of those items.
Bonus points to Creme for having a recycling program for their waste.
