A good Merlot. Not expensive. About $8 a bottle will be just fine. Concha y Toro is a good choice. Casarsa is another.
Look at what's on sell at Safeway.
Merlot is good with pasta with red sauce.
To really impress them, also take a chardonnay for before dinner BS'n
And a chablis for dessert.

Good Luck. Capt Brad.
