At Tankard and Tun, it’s easy to forget you’re in Pike Place Market, or in a room that’s kin to no-frills Pike Pub downstairs. Alas, the seafood menu looks promising but the execution needs work. So order a barrel-aged stout from the rotating Pike taps, and maybe a plate of cheese curds (anything fried is the best bet here) and savor the prettiest new spot in the market.
