The terminal B lounge is small and gets a little crowded in the late morning. There's a continental breakfast, and good beer selection. The staff are nice and helpful. If you request a shower (which I have whenever connecting), they send you to the multi-airline lounge down the hall.
There is a (newer, larger, nicer) SN lounge in terminal A, if you somehow end up over there.
