Love the Uptown area Y's...especially the Dowd. Very big, with lots of equipment on multiple levels. Even when it's busy, it's not that much of a headache to find an open machine. Every now and then, the basketball games get a little intense and the sound carries into the fitness area. Locker room is large and offers dry cleaning AND shoe shining, which I like.
Of the YMCA's near Uptown, this is definitely the best and the largest. Also has the most parking available too. Very welcoming, very clean and and great place to get your sweat on!
