Useless app
I tried placing an immediate order, and the app said it was searching for a nearby taxi, which it continued to show for several minutes. By this time, we were in a panic. We finally gave up and tried hailing a taxi - try that at 3:30 in the morning on a quiet street. One finally picked us up.
Today I tried sending a message to the company on their web site, and it said that my CAPTCHA was in error and would not send (I hate those stupid CAPTHAs with the pictures). Totally useless.
