Real examples: Faith & Flower, Juniper & Ivy, Work & Class
The most old-fashioned and difficult to write of all the punctuation marks, the ampersand is a classy way to combine two ideas into something larger. For restaurants, it lets them show the two sides of their personality, one of which is often a type of plant.
Real examples: Urban Curry, Urban an American Grill, Urbanbelly
Especially if you live in a big city, part of the draw of going out to a restaurant is feeling cosmopolitan. Putting the word "urban" in your name implies an air of sophistication, rule-breaking, and overall hipness. Also, that it might be near a subway stop.
Real examples: The Fifty/50, drink.well, Mint/820
Sprinkling a little punctuation into your name is like adding a dash of freshly ground black pepper. It spices things up! In a classy way. And it adds a bit of swagger to your step, because most people would shy away from such an unconventional move. In addition, your restaurant will immediately appeal to fans of e e cummings.
The address number
Real examples: Table Fifty-Two, Eleven Madison Park, 660 Angler's
A close relative of the street name, the address number is a naming convention at the disposal of nearly every restaurateur. Unless your restaurant is on a cruise ship, in which case you should probably just name it International Waters.
