Roseberry, Glendale on Brand Blvd.
I went to Roseberry for lunch today despite the rain. It's sandwiched between a Korean BBQ and Sushi restaurant- the smell of BBQ in the back parking lot almost swayed my lunch choice! The space is very clean and decorated with vibrant colors. Aside from the two counter people, I was the only one in there- but they were friendly and efficient. There are plenty of tables and chairs for people to sit at.
I have only been to Pinkberry once and had the Green Tea yogurt sans toppings; it was okay... a bit acidic for my taste. Roseberry only offers one flavor- a "plain" white one. It was really tasty- not too sweet, not too tart- just right. I had kiwi and raspberries sprinkled on top. A small with 2 toppings was $3.50 or so...
I do think it's a blatant rip-off of Pinkberry, but I don't live near one (yet anyways, I think I saw one starting in Old Towne Pasadena) so my loyalty reamins unassigned.
