Yes, Erotic Studio is through the heavy security gates (buzzer entry), and is open between 11.00am and early evening, 7/7. Blue Ice, round the corner - again, through gates (but smaller and leading through an entrance porch to a lift) - is open 10.00am (11.00am on Sundays) until early evening. Neither of them have hours such as exist elsewhere in the country (and, I believe, elsewhere in Brum), where they open through the night.
