^ I have designed and project-managed over 80 restaurants in both Canada and the United States. Rooftop restaurants are very difficult to operate successfully -- so they need some key ingredients:
- should have "snob appeal" with a well curated menu that is not too specialized -- steak and seafood fills the bill
- should have a view-centric cocktail lounge with entertainment (again well curated -- singer/songwriters or duets, trios and a mix -- music, comedy, magic -- that can buy into the slow nights. My experience with a restaurant that I owned in Edmonton (65-seat dining room -- converted at 10:00 p.m. into a dance venue with DJ (techno or disco) closed at 3 a.m. with "last call" at 2 a.m.; 65 seat cocktail lounge
- should have a well-landscaped exterior deck for al fresco dining -- your building should be able to handle something of a similar size to this (lounge plus dining plus kitchen plus restrooms plus deck).
- must have a delivery service to area businesses and residential (white glove service) and therefore a professionally developed website
- must have a unified connection with other participating businesses and hospitality venues and a cross--referencing platform (the more you help them the more they will help you)
- parking is a concern and needs to be strategically researched -- nearby businesses that don't need evening accessibility and can "lease out" there parking after 5 pm
- have a split shift on Monday through Thursday (11:30 a.m. -- 2:00 p.m. and then 5:30 -- Midnight) and then full operating hours from 11:30 a.m. until 3:00 a.m. for Friday, Saturday, and Sunday.
- do not supersede daily patrons for reserved guest bookings ever (unless they are willing to share the restaurant space with walk-in customers or unless you are in the enviable position of being able to book reservations)
- have a doorman/bouncer for the cocktail bar who works from 8:00 p.m. to closing (ideally an off-duty police officer who has force buddies)
- have full height enclosures for restrooms so that they can be unisex stalls with a common area for hand sinks -- you would be surprised how well people are behaved when the sexes commingle
- the cocktail lounge should also have other forms of entertainment -- darts, shuffleboard, bar-top video games and (very popular in my bar) backgammon (under bartender control) -- in the bar we also used to throw off-season parties with sponsorship from beer companies and liquor companies.
- interior design is key to establishing a distinctive aura or presence.
If you cut corners you will have a hard time making it as a roof-top venue. If you want to discuss let me know and I am happy to accommodate.
