Location may not be everything, but if you're an art gallery, you could do a lot worse than to be located at Gallery Center, Boca Raton's high-end mini-mall of seven individual galleries housed under one roof. On the down side, your competition is right next door. On the up side, anyone who wanders through the spacious Gallery Center complex is already likely to have art on the brain and thus be willing (and able) to shell out the equivalent of a year's salary for a prime work by a major artist. And if you're Habatat Galleries, there's the additional bonus of being the premier glass gallery in the entire region. The Boca outpost is part of a four-gallery chain that opened in Michigan in 1971 and has been focusing exclusively on glass since 1980. Along with hosting its own shows by such glass-world luminaries as Dale Chihuly, William Morris, and Dan Dailey, Habatat also curates exhibitions for museums and other institutions and offers a full line of consulting services for both experienced and novice collectors. Throw in the fact that Habatat recently presented the blown-glass orchids of Debora Moore — one of the best small shows of the season — and you've got a gallery that's first class in every regard.
