Food halls, food halls... everyone wants to build a food hall.
Here's my take - our group now operating in 3 halls in 2 cities, probably opening in 3 more this year (not announced), and taking 20 meetings after 100 proposals from Seattle to Miami..
There are a few varying public opinions on this trend: 1) it's over-hyped and short-lived 2) everyone is making a killing at food halls 3) popular chef-driven concepts are a perfect fit
1) It's not so much over-hyped or short-lived, but their success is misappropriated - more below.
2) 10% of the vendors at any given hall do really well, not all food halls are having success, NO food hall is busy outside of peak hours of dining (11-2 mainly as this is a great lunch, dinner not so much, but you'll squeeze a decent dinner 5-7).
3) Chefs have taken a liking to fast-casual as an escape from the high-pressure environment of their main establishments. The trick is: your concept has to make sense on several notes: a) it must be delicious b) it has to be easy to understand (helps if you already have a B & M of the same c) needs to be executed at a high level daily without the (chef) talent - as he/she likely has to spend their time elsewhere.
First and foremost, it's not a cash-grab. You can't charge $18 for a cheeseburger, even if it's Wagyu, in a counter-service environment. Using high level ingredients costs the same over a counter as it does at a table - and the cost of the dining room and server isn't 2-3x more than the counter service joint. Your ingredients are still your main cost of the dish regardless of what medium it's sold. When you serve a "chef burger" in a sit-down place that has a full restaurant menu, you can get away with a $18 price tag. Your premium burger ingredients cost (at most) $3-$4. To make a profit, you need to charge 4x-5x food cost (standard used to be 3x, but with rising cost of labor, rent, etc. you gotta shoot a little higher these days). In a dining room, with a (tipped) server, $17-$21 is the new norm for the "chef burger". You just can't get that $$ across a counter, but you're using the same ingredients and a $15-$17/hr line cook running the griddle/grill.
So the main idea: your food has to be delicious and affordable.. but also "cool", but not "too cool"... so - we're talking high end comfort food that's not too expensive. taking notes?
Food halls are a great way to bring a bunch of concepts together for diners in a densely populated area. Sharing overhead, designing a cool space (Revival is the best example of this), having a good bar program, music, etc. all add to the experience & value. However, a food-hall is not a "cash-grab" or as easy as Revival makes it look. Revival is successful because 14 top-notch concepts, that already exist and have systems/success elsewhere, brought their respective talents to a well-managed, well designed, well-run establishment. You can't invent a one-off concept for a food-hall and expect the same success. You can't get into the food hall biz without really knowing the restaurant biz. You need a myriad of great teams to execute a great food hall - the halls I have seen that only use 1 chef, to essentially invent 10-20 "concepts" are boring and bland.
To summarize: Food halls aren't a short-lived trend, but only the really well-executed halls will survive. Within the hall - only the very-well run concepts will survive and thrive, the rest will be constantly switched out.
