I had a shellac manicure at the Beauty Box, which was ok, reasonable price for London. The therapist did a good job, but I felt the polish was a bit thin and could have done with one more layer to be perfect - it seems to be lasting ok though.
The atmosphere at the nail bar was quite hectic, they were fitting in a lot of customers back to back. I’d use them again as it was convenient and quick, but go elsewhere for a relaxing vibe.
