Last week, I had the opportunity to treat my girls to a night out, courtesy of American Express Serve! In between shopping, holiday parties and end of year chaos, we set aside a night for dinner & drinks. Sans whiny kids.

We usually try to make it out for Margarita Monday at the Mexican restaurant at least once a month. For $.99 drinks, I wish we could make it every week! Typically, we pay for our own drinks, while one person picks up the tab for the queso dip we share.

With Serve, we can quickly split the bill on the mobile app, then send money through a digital payment service with the safety and security of American Express. Setting up an account is quick & easy. Visit Serve from your computer and get $10 just for signing up!

Once you have an account, they’ll send a Serve debit card for your account. It can be used wherever American Express is accepted. Which, makes me wonder if other perks come along with it. Like, being able to swipe a card at Costco. Or, advance ticket purchases. I haven’t had the opportunity to try it out yet, but it’s an interesting concept.

Plus, when you invite your friends, you’ll earn up to $50 referral credit. And, I do love sharing things with my friends! Like the amazing martini flight we shared last week at Houlihan’s. The mini martinis on the menu come in sets of three—and that’s too much awesome to have alone!

I went with Adam & Eve, Blue Moon and Guavatini. Wait. Let me rephrase that. The amazing Guavatini that tastes like cotton candy! I’ve been on the hunt for this cocktail since the first time I sampled it earlier this year.

I couldn’t remember what it was called, but I never forgot the taste! I have ordered a different cocktail every time I’ve been to Houlihan’s since, in search of the elusive cotton candy cosmo. I guess I should have tried a sampler flight a long time ago.

Of course, now that we’ve tasted them all, I’m going to have to go back to a full size Guavatini. So, so yum! I’m so excited to finally find it.
