It's an old Chinese proverb that cheap things are not good, and good things are not cheap, but they artificially manipulate their currency like jerks, so that's probably off. Proving it is: Frugal Foodist.
Started by a lifelong Philly restaurant nut whose pastry-chef mother encouraged a love of food while his father instilled the unique joys of being a tight-wad, easily-searchable FF keeps you corpulently current on all the best deals in town -- like the ads in the back of the indie rags, only with a less sausage-centric menu. Updated a handful of times a day as stuff comes in, FF serves up commentary-/info-laden posts mainly focused on coupons and daily/weekly specials, along with limited-time offers for cheap food and drink, free food, and (best of all) free drink, which could previously only be acquired by throwing on a ski mask and robbing the liquor store, but once you factor in the opportunity cost of the overtime you've missed while doing it, it's really not free at all. Recent posts: free wrap giveaways from Wrap Shack, a 10-spot drink & snack dealie at Bistrot La Minette, an all-you-can-eat sushi thang at Pod, $1 sliders at Tavern 17, two hours of free drinks at Tabu & DiBruno Bros, plus more-editorialized stuff like a rundown of which joints accepting crazy-discounted Restaurant.com gift certifs are worth hitting, and a treatise on the dangers of prix-fixes -- mainly that, just like betting on any game reffed by Jim Delany, they're fixed.
FF's recently launched its Deal Calendar, featuring a new map function that'll help you scout the locations of free burgers and half-priced Kensingers, to back up another Chinese proverb -- the man who eats and drinks the most, shall develop the diabetes.
