This place rocks!! They keep changing their flavors, that's probably why reviews might vary depending on the flavors.
For me so far, it's one of the best spots in Pittsburgh and totally worth a stop couple times a week while it's summertime.
In general, if there is a smell of fresh hot waffles being made, I'm sold! That fragrance brings back lovely memories and starts a French folks symphony in my head. That's what exactly Millie's did to me. The pleasant awesome smell of fresh waffles can be detected from a block. Homemade ice cream especially the cantaloupe sorbet and rose pistachio are flavors I have never had before and they were just sublime!! Tried the rose pistachio twice and it was insanely tasty! I'm not a fan of cantaloupe! But, there was a guy offering flavors tasting at the entrance to make the long line move faster and he recommended the cantaloupe sorbet. Once you taste this cantaloupe sorbet, it's like an enormous burst of freshness in your mouth!! It was just perfect! Not too sweet, not too heavy, but at the same so refreshing and flavorful.
My friends (from Pittsburgh and one visiting from NC) loved it too although they're not ice creams fans.. One insisted on going back next day. It added more credit to my foodie CV although my foodie board certification is uptodate and with honors.
If you're visiting Pittsburgh, you totally should try this place. Parking is easy and available at a plaza close by (where Chipotle is). Also there is Adda coffee and Starbucks nearby if you (like me) feel like a cup of black coffee after a dessert like this.
