Check out Groupon Pages for great insight on Restaurants!
Groupon has been expanding into different verticals recently. Their bread and butter is still deal-a-day vouchers, but they have a massive selection of online coupons and have now created a sort of directory of sorts for restaurants around the country. There are real reviews about the places, detailes, maps, business information, etc.
You can check out an example here: Tampa Pizza Company. Groupon Pages are very well laid out and helpful and can be a great asset next time your traveling on business or pleasure!
