Every time I visit Mid Valley, I'll try to pay a visit here. I love their ice blended matcha green tea, although I think it might not be available anymore. Otherwise, I'll go for their strawberries and cream. For a good dose of caffeine, try the 'volt'. You'll probably stay awake the whole night after one of these. Hehehe.
I've always preferred Gloria Jean's compared to other coffee joints as their staff are always friendly and helpful, and the shops are clean and comfortable.
