Calgary's Stephen Avenue is right in the middle of the city's oil and gas towers. Several high-end restaurants thrive on corporate business lunches and boozy dinners, but even they aren't immune to what's going on in the economy.

Teatro is promoting its cheeky "multi-level economic stimulus package." One of the features is a three-course lunch for two people — for the price of a barrel of Western Canada Select crude oil (which closed at $53.93 on Thursday).

If it goes above $60 per barrel, the restaurant promises to help you celebrate with a carafe of wine for the table.

Every weekday from 3 to 5 p.m., Teatro is also slashing the price of every beverage, and every bottle of wine in its impressive cellar by 50 per cent.

Several blocks away, Saint Germain has waived the corkage fee for people who bring their own wine, and is pushing a three-course dinner — available every night — for $39.

At the other end of the spectrum, sandwich chain Quiznos has launched a 13-inch sub for $4.99 to give customers "more sub for their dollar."

Available in pesto turkey, Italian, turkey club, tuna, and beef, bacon and cheddar on a ciabatta loaf, you can get more than a foot of sandwich for less than five bucks.
