but when you click on any 'order' button for any of the four restaurants, it takes you to here, which is the site you get to via Facebook. https://www.illegalburger.com/online-ordering/
Note the subtle difference in spelling of the sub-page, "order-online" (old) vs "online-ordering" (new).
Now, before you stifle your yawns, take a look at both old and new pages.
Old: All 'original' four locations are listed. New: Only three are listed. The ARVADA location is missing.
The Arvada location has the same street address as the new Takiza Taco place: 15400 W 64th Ave, Arvada, Colorado 80007
However, as discussed before, a certain look at the location via Google Maps https://www.google.com/maps/[@ userid=105].1725601,20.87z?authuser=0&entry=ttu
shows the Illegal Burger on the far right end, and the new Takiza Taco place 2 units to the left. Using Firefox, it take a couple of mouse-wheel clicks for me, zooming it, to get both places to show up by name.
[My results vary using Edge;sometimes I see one or the other. Using Chrome only shows me the Illegal Burger and the old chiropractic place.]
which is a menu page with all the items, where a) the items have prices and b) you can click on the items to order. BUT, at the moment I can a pop-up box with an overlaid pop-up box that says "Oops! This menu has changed". When I X-out of that, it appears to allow me to select the item and add it to my "Cart." When I X-out of that 'add item to cart' box, the URL changes to: https://kalakamexicankitchen.getbento.com/online-ordering/kalaka-mexican-kitchen-evergeen/menu
This has a similar style to the Illegal Burger main page, where the sub-page says "order-online) and I am given a choice to click on either location, Evergreen or Denver.
Except for the URL difference, it looks like the new-style order page for Evergreen.
I can get to the new-style Evergreen page by clicking on "ORDER HERE" for Evergreen and confirming that I want to order from there.
So, "START ORDER" from Facebook is missing the (new-style) selector page to select the location to order from.
-- REAL-TIME observation: 'they' must be watching me, as I've gone back to the Illegal Burger Facebook page and clicked on "START ORDER" and it now takes me directly to the old-style Illegal Burger order location selector with all four locations.
