I've been to the O'Connor location of Eggsmart once, but have been to other locations as well. They're a great chain of restaurants that serve good food for not a lot of money. They serve only breakfast type items, but that's okay with me! Service is a little weird. I don't think the waiters have specific tables, but it seems to work for them.
The only downside to Eggsmart is that they're only open till 3pm, so you can't go there for dinner.
