Restaurant Eve! They have an amazing "Lickity Split" lunch special. $13.50 for two items off the lounge/bar menu. Mon-Fri 11am-4pm. A fantastic deal, especially since this place is such a high-profile restaurant with an otherwise higher price tag!
I didn't realize that Eve took reservations for the LS lunch. When I've gone, I just walk right into the bar and take a seat if open, after telling the hostess or host that I'm there to eat at the bar/lounge. Was never asked if I had a reservation.
When I've been, it's been a first-come, first-served for the Lickety Split. Dining solo has been easy to get in, but in 2+ groups, there's usually been a wait, from 5 minutes to half an hour, depending on how busy it is that day.
Ditto to the LS lunch at Eve. If you go a little later, it's easier to get a spot for more than one person. If you're solo, you shouldn't have much of a problem. If you're in a fish and chips mood, there's also Eamonn's on King St. (same owners as Eve and the Majestic).
