Nurses wear many hats.
Just tossing out a few menu suggestions from the different departments I used to call home...
This is for breakfast, right?
Floor nurses rarely have time to sit down to a meal, they enjoy "finger" type foods that don't require re-heating to stay tasty.
I know it may sound old hat and boring to you, but as the offer for free food is rare (they have to use what is stocked, at the best price, by admin, so the "drones" rarely get to partake of anything from outside salesmen) most are grateful for a great selection of fresh bagels and toppings. Don't forget there are 2-3 shifts. Insist that your client provide for the often forgotten nite staff.
Inter-department council..this would be a sampling of staff from all departments. They have lots of weight (and $$$) to throw around when it comes to purchasing and reviewing new products/meds. This group is used to the free meals, so will be the ones your clients want to impress. The breakfast casseroles, assorted breads and pastries and fruit bowls have been done to death (not sayin' to remove from your menu, just try to reinvent and upgrade). This would be a good time to make omelettes and pancakes to order. The "pump" canister coffee in assorted flavors with a good choice of creamers is always a hit as is an espresso machine (don't forget the barista) depending on the budget. This is a group that is used to having real plates and flatware and coffee cups, as well as glass pitchers of juices on the table.
The ED is usually so chaotic that they will eat anything (yes, even a box of stale cookies/donuts from Sams/WalMart/Krogers). I remember one savvy sales rep that would call in advance for orders and show up with rich,thick hot cocoa and fresh, hot breakfast tacos from our fave TexMex hole in the wall, or the time she brought the taco truck for the nite shift.
Doctor's offices..this will be the bread and butter of your client's meal ticket. The days of free trips to "conferences" is long past. Office staff have more time to sit and listen to a rep's spiel reguarding (insert the new wonder drug or product here). The staff supervisor will often be the one who decides what gets ordered. Not sayin' you have to show up with Eggs Benedict (that would be for the hospital council, lol) as the casseroles and fruit bowls and breads will still be popular with this group. Especially if the rep comes bearing a bag of ziplocks to "preserve" any leftovers for a pm snack (I am saddened to hear that the coffee cups and note pads and pens (my personal fave) are a thing of the past). The pancakes and omelette offering would be a huge hit if the budget allows.
Wow, that was a long post!
Hope ya'll can cherry pick a few ideas from all that verbiage, lolol!
