As others noted, knowing tastes makes a big difference. Lots of good
Champagne options, but if you prefer Extra Dry, Brut options like most
tete de tetes might not be best choices.

Also, do you have a plan for serving? If with a group, maybe consider a
dessert wine, where smaller pours are plenty. But if just you and your
SO, maybe a table wine to savor over dinner. Lots of great wines (for
my tastes) for $150, but a glimpse at what you like might enable folks
to make better suggestions. What have your favorite wines been?
