> My girlfriend and I will routinely pick a place to eat on a Friday or Saturday 30 minutes before we intend to eat. I don't like having to call a half-dozen places in order to get a table, and I wouldn't have much choice without these systems.
It never even occurred to me to try and make reservations _30 minutes_ before I want to go eat. Interesting concept. I usually just aim to only go places where I know I'll be seated very quickly, or else get take out.
If the restaurant is unable or unwilling to report their true availability, then the value of OpenTable decreases dramatically.
