1) Increase in general revenue and increase general presence in the local community. Allows for access to liquor licence which would greatly augment show openings (shows open biweekly-to monthly). Also to provide a social space for an upcoming art scene. An exhaust system, I think anyway, is important. I do not think the layout would preclude a well sequestered kitchen that would vent out into the back. The landlord is looking at redoing the heating in the building and installing heat pumps so it wouldn't be a bad time to look at it.
2) The environment is not a static space. These are all curated shows, usually more than just paintings. Sculpture, mixed media, etc are represented. This is gallery focused on art sales and rentals, not merely a place for display. Smaller pieces and artisan jewelry are also on display for sale. Shows and materials change frequently, and at this point the menu of whatever foodservice is developed will follow along with that model.
3) I have.I have also done caterings and pop ups in several galleries over the years and can tell you that their safety concerns are all over the place. Our provincial gallery, for example, will not allow red when or coloured spirits on the premises. Not for risk of spillage but rather for volitals that enter the air when opened. I was curious about any less "academic" experiences any members might have personally had. Horror stories, truth be told would be more than enlightening!
4) As I hinted, the design is open to ideas right now. We want to maintain an overall "look" with the new room. Just how connected the rooms is tbd. The new space will need to display some work, obviously the safety and fragility of the work will play a part in where it is displayed. Where seating is set up will also play a part in that.
