The idea behind GrubWithUs can seem strange at first — but once you’ve had your first meal with them, everything just sort of clicks. You pay, you sit, you eat, you meet people, and you leave. They handle all of the annoying bits (the check splitting, the tipping, the … finding people for you to eat with) and you handle the eating. Easy.
Making things even easier, GrubWithUs has just launched a shiny new iPhone app. Emphasis on “shiny”.
