Pacific Poker

Pacific Poker has grown by leaps and bounds in the last year and now offers and aggressive player incentives to entice you to play.  It also happens to be one of the most lucrative places for a solid poker player to earn a lot of money.  This is partially offset by a remedial interface, poor hand history support and slow game play.  Still, the number of very inexperienced card players on this site make it a good place to increase your bankroll.

On the down side, they now longer support US Players (at least until an exemption is given for online poker play to the current law). That being said this is still a good place to go to find some of the weaker players.

They have a no-nonsense interface (shown below) which, although it misses some of the bells and whistles of other sites, keeps your eye on what's important -- the action!
 

The poker table interface is basic, to say the least.  Game play is strangely slow and at least some of that seems to be due to the communications software in the interface.

The best bonus is the great action and players at Pacific Poker, though.  A perfect chance to test your newest strategies and increase your bankroll.

The lobby, though basic provides everything you need to find and join a game.

Promotions

Pacific Poker offers a first time deposit bonus of 25% up to $100 as well as a bonus points promotion which allows you to convert your time played online directly into cash.  They are one of the (if not the) only site that provides a player points to cash conversion.
