I guess it just depends on what you want to see. Amsterdam is a very nice pool room. Beautiful bartenders and waitresses. Well taken care of gold crown 4s. A lot of good players and some pros several times a week.
It's also very pricy (especially if you're not used to nyc prices), there's no action and a lot of times you'll have to wait a while for a table.
I would suggest Steinway in Astoria, Queens. They have weekly tournaments Monday and Wednesday nights. A whole lot of good players. Always action, great Greek food and prices are a little more reasonable.
