Yes, and it's a bit of a walk from where you arrive from DL flights. It's at the far end of 2C, right before 2A starts, on the departures level. The entrance has a carpet and a couple potted small trees.

AFAIK a D1 arriving boarding pass works fro entrance, but not DL or SkyTeam status. AF business or first class should obviously work also. SkyTeam ElitePlus status arriving in coach on DL apparently worked until a couple years ago as I remember overhearing a discussion about this between a DM passenger and a dragon.

Note that the lounge closes in the early afternoon, IIRC about 1-2 pm. Note also that the F&B offerings are strictly (nice) breakfast with no alcohol like wine or spirits, although I didn't look for beer.
