This shop carries the best in tennis necessities, including top brands of racquets, but that's not all. Unlike the big sports stores, this one's got everything to meet your racquetball, badminton and squash needs. Plus, its experienced stringers will hand-string your racquet the same day you bring it in, if not right then and there, and you can customize the strings and tension. Despite Grand Central Racquet's address, 341 Madison Avenue, the storefront is on East 44th Street between Madison and Vanderbilt Avenues. There's also another location of the store nearby, inside Grand Central Terminal (hence the name) between tracks 38 and 39.
