To expand a bit on what Anthony said; I wouldn't necessarily trust whatever hours they tell you. They rarely have anyone there and if they do, they're not likely to be any good at sharpening skates. The one time I had my skates done there, the guy said he didnt know how to do anything other than a 3/8 hollow. I'm a goalie and i was desperate so i suffered through until my next sharpening but yeah...
Yes they have a pro shop (limited stuff though) and do skate sharpening. In terms of hours, it varies depending on day and when the guys there. I would call and they can probably give you hours.
