Second level in a coffee shop, who wants to go there
A coffee shop can never have enough seating area!
This new EmeraldPark TimHortons store will be replacing the SheppardCentre TimHortons store which is the size of a 1-bedroom condo; it only has a few seating area and many are just ledges/shelves against the wall or window. Here's an image (from zomato.com) of the SheppardCentre TimHortons (notice how those folks are sitting, even their feet are encroaching onto the mall's common area):
From a customer's prespective, the current SheppardCentre TimHortons is always packed but they've been losing customers for years,.... if customers can't get a table, they go to the next coffee shop with table,... and free wifi. Nearby along Yonge Street in NYCC, there's practically a coffee shop on every block: SecondCup & TimHortons in SheppardCentre, 7-11 & McDonald's at northwest corner of Yonge&Shepaprd, Cafe at WholeFoodsMarket in HullmarkCentre, Starbucks in Avondale (another Starbucks on 2nd floor of EmeraldPark), JavaJoe in NestleBuilding, each gas station (Esso, Shell & PetroCan) have their own coffee shop, cafe at lower concourse level of ProctorGamble building, Druxy, CountryStyle, m2m cafe, Bake Code, etc,....
Needless to say, a lot of these customers live in condos and just need a more spacious place to get away from their cramp quarters to just hang out with their laptop or to socialize with a few friends; and they'll be taking the table for an hour or so instead of the 2 minutes it takes to drink a cup of coffee. Thus, coffee shop can never have enough seating area,... as soon as they're full, they lose customers to their competitors.
The EmeraldPark TimHortons space is interesting in that it's 3000 square feet with about 25 feet ceiling height,.... this TimHortons will have it's own in-store washrooms and likely another business in the TimHortons store,... which means there will be less and less room for seating areas,... keep in mind each of these units cost about a million dollar each, so the best way to build will be upward into a second floor seating area - given that they already have 25 feet ceilings,... look at the previous image of how huge the floor to ceiling glass windows are,... at a coffee shop, the first seats to be taken are always the window seats. People go to coffee shops to wake up and sunlight by the windows give them that extra boost, vitamin D and Yonge Street watching,... and yes, for those who want to snooze, there's non-window seats in the back away from the sunlight.
As TimHortons move more into ready-made food business,... the biggest competition for the EmeraldPark TimHortons will be the cafe at WholeFoodsMarket at HullmarkCentre directly across Yonge Street which is packed and has plans to expand since it's by far the busiest part of that supermarket.
From a business perspective, second floor seating is a necessity of urbanization. Since EatonCentre opened 40 years ago, every single McDonalds/McCafe (current and old) on Yonge Street between College and King Street (outside of EatonCentre) have always had second floor seating (ditto McDonalds/McCafe at Queen&Spadina and for old McDonalds at Bazis Exhibit site). Why? These are businesses in competitive market (fast-food/coffee industry) where margins are razor slim and profit are based on volume,... in order to generate volume, they need lower cost seating area (which exclude knocking down the store next door for more street-level seating),... that means building upward.
From a planning perspective, if EmeraldPark TimHortons store were to request adding a second floor seating area within their store; that design would first have to be approved by the building management, then city planning since retail area increases and the previously approved proportion changes (retail vs office vs residential), might even need amendments at North York Committee of Adjustments,... basically it could be a longer process.
