If you're going here to see some Gretzky memorabilia, you'll see it. If you're see to watch sports, you'll see that. If you're here for great tasting food or reasonable prices, you will be disappointed.
In other words, it is what it is - a tourist spot designed to prey on your love of The Great One and to separate you from as many dollars and/or looneys as possible. The atmosphere is cold and stark. The wait staff is instructed to move you out as quickly as possible. The beer selection is mediocre at best. You probably won't see any reason to return after one visit.
Of note, there used to be a bubble hockey game in the corner, but they took that out, probably to squeeze in an extra table or two.
