Eastlake is a great neighborhood to live in as a cyclist. I really enjoyed my time there and hope he will too. No breweries involved, but the ride south along Lake Washington Blvd is fun and scenic, and you can make a loop of any length you want. Can't recommend it enough. Ride down along the shore, come up Beacon Hill, ride home through downtown or Capitol Hill or whatever seems interesting that day. Or go around the S edge of the lake and take one of the floating bridges back. Lot of beautiful parks, mountain views, water in every direction. Eastlake is a great place to start and end that ride.
If he has pets, the vet there is expensive but excellent. I moved across town and we still go there.
