I saw this article on ice cream cakes. The reviewer tried three different stores
Cold Stone Creamery ($40.00);
Baskin-Robbins ($46.00);
Dairy Queen ($29.00)
She said that the best was DQ so spending a lot of money for a cookie or ice cream doesn't make it the best.
I tried ice-cream cakes from 3 popular chains, and the best was also way cheaper than the rest
