Well, what is your favourite restaurant? Mine has to be White Spot and their Triple-O sauce, absolutely amazing.
There's a Korean restaurant in Sydney CBD named "Seoul-ria, and while the food doesn't seem very authentic when compared to some other Korean restaurants I've been to, I love the atmosphere. There's a button that looks like a doorbell on each table, and when you push it, a waiter/waitress will come to your table within 5 seconds (usually). There's just so much staff working there, it's incredible. The staff is probably underpaid though. They always seem to be in those types of restaurants (ie: ones with too many staff members). The man who owns that restaurant must be one of the absolute richest men in the restaurant business in Sydney. The number of people who line up to eat there is staggering. You wouldn't believe it until you see it.
Oh God, I'm rubbish at remembering names. I've only been there twice. It's in a modern looking building just off Piazza San Marco in Venice, if that helps
Anyone who lives in the Bay Area, CA ought to know Zachary's Pizza. Their deep-dish is honestly legendary, and for good reason. In other genres though, India Palace In Moraga has incredible Indian food, and Las Palmas (across the street from Zachary's) has some of the best burritos I've ever tasted.
