Per AlpineK, the Montlake bridge may be closed.
If so and you're coming across SR-520, take the next exit (Roanoke I think), at the light hang a right and head down the windy road (Interlaken), at the stop sign at the bottom, you can either go straight or right. Grady's will be in between where these two intersect 25th Ave (or 24th or whaever the name of this arterial.)
