All-Inclusive Group Dining When meeting planners book a corporate group event through Lip Smacking Foodie Tours, the entire group is assured a top-notch dining experience with three to four signature dishes at each restaurant. Our affordable tours are priced per person with tax and gratuities included. The only thing not included are drinks. However, a beverage package upgrade is available, which provides guests a signature cocktail at various stops. Build Your Network Our exclusive experiences provide the ultimate networking opportunities. At a typical sit-down dinner, you’re lucky to engage the person to the left and right of you. Because our tours take place at multiple restaurants, with walking in between, there are countless opportunities to interact with different people when you sit down at each venue and as you traverse along the way. Our experiences not only provide more ways to network, but a more convivial way to do so. Large Groups Welcome Lip Smacking Foodie Tours is ideal for groups, small or large. Our experiences can accommodate groups from as few as 1 to as many as 500 guests, making us an ideal choice for any corporate group event. Stress-Free Booking Process Booking a tour is stress-free and allows you to enjoy the company of your guests more easily. You’ll take comfort knowing that everything is taken care of from the moment the tour is booked to the minute it concludes. Since the menu is already set, you have nothing to worry about. Just remember to submit ahead of the tour date any dietary restrictions and food allergies for anyone in your group. Feel Like a VIP at Each Stop With Lip Smacking Foodie Tours, you and your group members never have to worry about waiting in line to get into a top restaurant or being shown to a less than desirable table. On our tours, everyone is treated like a VIP with immediate seating upon arrival. What’s more, your group may receive a special warm welcome personally from the restaurant chef. Menus can be printed featuring your logo, too, which can be an added bonus for all those Instagram moments you share. For added ease, we can even arrange transportation pick-up and drop-off, as well as an event photographer. And for groups that desire an extra luxe experience, we can also arrange for an evening helicopter ride over the glittering lights of The Strip. A Memorable Experience for All Lip Smacking Foodie Tours offers a way to gather and dine that few have experienced, and all are sure to remember. Our one-of-a-kind tours are special, from the first stop to the last. It’s an experience that attendees will reminisce about long after they leave. Location, Location, Location One of the best reasons to book is the convenient and efficient way the experience is designed. All restaurants are within an easy walking distance of each other. The short stroll allows your group members a chance to engage in prime networking opportunities before heading to the next place on your tour itinerary. You Get a Dinner and a Show Our tours offer an exquisite feast plus entertainment. All tours include a knowledgeable, professional guide who leads the group on a walking tour, offering engaging tidbits and fascinating stories. Several other interactive experiences are included along the way exclusively to our tours, ensuring there is never a dull moment.

We offer a way to try some of the finest spots in the city and dive into various cuisines and dishes. All the pre-selected dishes are curated to our high standards to ensure they will delight any palate. Tours Available from Day to Night With any corporate group experience, booking flexibility is key.
