But if you keep more evening hours, there's nothing wrong and everything right with cocktails in the Mandarin Bar, offering that same stellar view.
Another cliché Vegas date that deserves every bit of its reputation is a stroll through the Bellagio Conservatory & Botanical Garden (maintained and updated each season by a horticulture staff of 120) and the iconic Fountains of Bellagio -- both of which are also, helpfully, free.
For some of the best in town, hit up local coffeehouse Sunrise Coffee for an excellent pour-over made from their own Mothership Coffee beans sourced from single-origin organic Fair Trade micro co-ops (that's coffee-talk for real, real good), then cross the street to Sunset Park for a stroll along the pond filled with geese and ducks and swans (romantic if you suppress thoughts of all the bird droppings), or through the ancient dunes that once covered all of Las Vegas (the dune field is all that remains of them).
Double Helix Wine & Whiskey Lounge is kind of the ideal date spot: centrally located from most corners of the Las Vegas Valley, right off the I-15/215 interchange, on the Strip without being on the Strip, in a neutral location with tons of free parking, good food, and drinks all around, a stellar happy hour to keep it cheap, and a great patio with comfy couches and warm fire pits.
Atomic Liquors is the oldest freestanding bar in Las Vegas and a beloved local dive, as well as a beloved local beer bar (still one of the best in the city).
Just last year they expanded their offerings with the Kitchen at Atomic, a separate full-service restaurant that shares the same property and outdoor patio as its namesake.
Gold Spike is basically a hipster romper room complete with adult playsets (think giant versions of Jenga, chess, and foosball).
The current exhibit is "Samurai: Armor from the Ann and Gabriel Barbier-Mueller Collection." Don't let the name fool you: Khoury's Fine Wine & Spirits is actually probably best known as one of Las Vegas's best craft beer stores (and bars), though they most certainly sell wine and spirits, we've heard. Every Wednesday is a new beer tapping event, often celebrating a new special release or entry to the Vegas market, followed by wine tasting events every Thursday.
The folks who work here and those who hang out almost daily are super friendly, so taste some new beers (or wines) and plan on making new friends together in a low-pressure, casual, fun evening here. If so, start pulling out the big romance guns, and start with a trip to the top of the Eifel Tower inside Paris Las Vegas, a half-scale replica of the real deal, then have dinner at the Eifel Tower Restaurant, with a wall of floor-to-ceiling windows offering an unparalleled view of the Bellagio fountains.
The restaurant is a sunny, airy, open, reclaimed-chic space rehabbed from an old auto shop that serves excellent, seasonally changing elevated gastropub fare.
Belly up to the bar to chat with the knowledgeable bartenders about what's good on the menu and off the beer list, and enjoy a casual night out that's still a best face forward in local food and drink.
