A ballet school run by the mother-daughter team of Pamela and Zara Hayes has relocated to a prominent Midtown building near Memorial Auditorium. The British former prima ballerina and her daughter, who followed in her dancing footsteps, just moved "Pamela Hayes Classical Ballet Training" to a vacant building at 17th and I streets last week. The ballet school's move to the block is seen by the property owner, Aaron Zeff, as a good fit with a restaurant row he's proposing to develop on the alley. The school left a temporary shared space at 1925 U St., on the outskirts of Midtown, for a place in the heart of the central city. The school had operated in Curtis Park for about 15 years before
