If I could pay my bill by using my Smartphone at Purple...

As a restaurant, Purple Café and Wine Bar has a huge advantage in the mobile industry, because so many compatible mobile apps already exist, that Purple could join the mobile revolution with very little initial cost on its end. Mobile apps, like Tabbed Out (powered by PayPal), UrbanSpoon, Yelp, and even GroupOn and many others, all put the power of mobile into the hands of both restaurants and their guests. With that in mind, I've determined that Purple should adopt more of the following:

Searching for Yelp on Purple - it looks good! Yumm

1. Create a serious presence using Yelp! Yelp is one of those great apps that is all user-generated. The guests' great experiences drive the Yelp reviews, and when a company wants to get people coming back again and again, it's vital to have a strong presence on Yelp, as so many individuals use it. Moreover, Yelp gives the restaurant a way to gauge its performance while serving customers. If the customers have complaints, although it pulls down the restaurant's average ranking, the restaurant can listen and react to those complaints so that when people come in to try the restaurant that they can think, "Wow, I don't know what that critic's problem was. This place was awesome!" 
2. Use Tabbed Out or some similar self-payment service! Tabbed Out is a relatively new mobile application, powered by PayPal, which allows patrons of a bar or restaurant to pay their tab from their phones. This may seem risky - "Oh, if I don't bring the guests a check, they'll never leave." On the contrary, this method gives guests the power to pay for the check at their own speed. As the computer will notice when the customer has paid, and because they've agreed to pay for the tab from their phones, the company's account will keep track of the individuals paying from their mobile devices. On a busy Saturday night, when individuals are rushing up to the bar while waiting for their table, or when they want to get going at their own pace, Tabbed Out helps customers stay satisfied, because they don't have to wait for the waiter or bartender to bring the check. They can pay for it themselves without waiting just to receive the check. 
3. Utilize mobile couponing - FourSquare, LevelUp, GroupOn, LivingSocial and more… All of the aforementioned apps make it easy to find great deals in your area. If Purple was to start using these apps, guests would have an incentive to pick that restaurant over another while they're walking downtown. With GPS location devices hooked to every SmartPhone, if they were within walking distance of Purple, their phone would show that  a daily deal of some kind of was occurring, and on-the-fence guests could go and enjoy a free glass of wine with an entrée priced more than $20, or a half-priced dessert when you've ordered two entrées that together cost over $60. These kinds of promotions would give guests the opportunity to try what Purple's menu has to offer, and they would thereby be given more chances to fall in love with the restaurant, the food, and the ambience. Furthermore, apps like FourSquare and LevelUp make dining out a game, in which guests can compete with other guests or friends to become the most loyal customer or to be receiving the best deals. What better way to win over customers than make it fun while they're visiting?
4. Teach the guests about wine with a mobile app! Purple's name alludes to color. Although the color is probably most directed at the purplish tones of a dark red glass of wine, or the color of the grapes, color could also be thought of as the color that describes one's mood. Purple could make a mobile wine app that matches wine with the mood or taste preferences of the individual after they complete a quick (3-5 questions) survey: "Seems that you're feeling yellow mellow today, so try one of our deep Merlots to sink back, or try one of our crisp Chardonnays to lift your spirits." The individual might also be able to browse through all of the wines available from their phones (instead of a paper menu that can become worn over time), and by tapping on the name of a wine, they can learn more about it. By offering customers a mobile application that puts the information about the restaurant's specialty in their hands, they have the best motivation to truly enjoy their choice, and to find incredible value in the experience.

These are just some ways that Purple would do well by using mobile technology. More ways are certainly possible, but from first glance, it's already obvious that if Purple isn't using mobile technology enough already, it had really better start, so that it can get ahead of its competition and really stand out from the crowd.
