We like it for the reason posted in the headline: there are lots of different beers. The beer menu is so long that it is overwhelming. Even if you don't like beer, there are a number of other delicious drinks. There is also a heated patio facing the park.
You can sample local beers (from the Pacific Northwest), and you can get a flight of four beers on tap for a fairly reasonable price. The views on the park are also really nice. It's a great place to chill for a evening, afternoon... or, morning. :)
The chefs won't alter the menu, so if you have special dietary needs, call ahead.
