I live nearby. They're not really on W. Colonial as the directory claims, the entrance is on Clarke Rd. north of the Michaels store. There's easy access from the 408 Expressway coming from Orlando, and back onto the Expressway heading towards Orlando. To get to the Turnpike, you'd have to use the Expressway entrance at Good Homes Rd a mile or so east, or drive further west on SR 50/Colonial Dr. to the Turnpike entrance. None of the photos on the app are actually near the site.
The directory says food & restrooms. The only fast food close by is a Honey Baked Ham across Michaels parking lot, and there's one or 2 small ethnic sit-down restaurants in the adjacent strip mall to the north. I guess the restrooms would be in Michaels or the PetSmart a couple of doors down, during business hours only.
West Oaks Mall is mostly abandoned or converted to office space. There are still a very few food stands open in the old food court, but there's no direct walking route to the mall. You'd have to walk out up the street and then into the mall entrance road, or walk on a maze of back driveways with no sidewalks. I think it would be about a half mile walk.
