Wording for non-rehearsal dinner

We're having a dinner for immediate family and bridal party the night before the wedding. For all intent and purposes it's a rehearsal dinner, just without the rehearsal (since we're getting married at the hall). So I don't want to call it that on the invites.

The only things I could come up with is Pre-wedding dinner, pre-wedding celebration, or non-rehearsal dinner. I'm no too fond of any of those. Does anyone have a better sounding idea?

This is what ours said (we also did not rehearse) - it was immediate family & OOT relatives:

Help us celebrate
on the eve of our marriage
Cocktails, dinner and Games
On Friday, April 30th
beginning at 7PM

Dave & Buster’s

We used:

A Happy Bride
A Groom Beaming with Pride
And all who will be
Standing by their side!

Melissa and John invite you
to join them for dinner at
The [Restaurant Name]
Time, Date, etc.

And, then in the lower left-hand corner we put:
