I went to Yummy cupcakes on Magnolia in Burbank two days ago...had a so-so experience. I was a little disappointed to see that they were sold out of 1/2 the flavors by 3:30 PM (they close at 7 PM). The staff was not very enthusiastic and seemed disinterested. However, the site was very clean and had a warm appearance...nice displays and menu boards. I was pleased that the portion size was reasonable (I dont need 1200 calories of cupcake) as was the price ($2.50).
I ordered the lemon tart cupcake. I was pleased with the strong flavor (TART is accurate) and the cream cheese-lemon frosting. However...it was way too sweet....(and I almost never complain about the sweetness of desserts)...sugar could be cut by 1/3.
