Restaurants I'd recommend... Coastal Kitchen, Skillet Diner, Lost Lake Cafe. All of those are located in Capitol Hill.
Beer/Whiskey... Radiator Whiskey by Pikes Market and Chucks Hop Shop in the Central District. Chucks has over 100 different beers on tap.
The Seattle waterfront is currently under construction and is a mess so I wouldn't really recommend going down there for anything other than Pikes Market. If you go into Beecher's cheese at the market they usually have free cheese samples in the back. AMAZING stuff!
Would also recommend visiting Volunteer Park. There's an old water tower in the park that you can go to the top of and get a great 360 view of the city and it's FREE.
Fremont and Ballard also have a lot to offer.
Enjoy your trip!
