I've gone by myself and ate right at the bar no wait
No need usually. You can call ahead to see if there's a longer than expected wait though.
Reservations are generally not needed
Red Robin does not accept reservation s for small groups.

No reservations needed
Not unless you have a large group. Then calling ahead would be a good idea. Otherwise I've never seen more than a 10 minute wait
