Even the restaurant formerly known as Toad's has succumbed to the Groupon peer pressure. Check out today's offer: $20 for $40 at South End Grill 'N' Bar. Expires Sept 8 and they clearly call out that you must order a food item (so I guess we can't just drink away our $40?). But a limit of three per person. Within the uHood we could buy a bunch and just eat a South End every week until September! (not that I am personally endorsing this strategy)http://www.groupon.com/san-francisco/ What is next – a groupon for Clooney's?
