Fuel also has outstanding hot/cold subs, and a possibly re-opened self serve froyo station that might have something reaaallllyyy close to Dole Whip. Do not sleep on Fuel...or Picabu, or Kimonos, or The Fountain, or Il Mulino...or Fresh Med (if they are open.) I'm a big fan of the quality at Swolphin. I wouldn't hesitate to have some hot subs from Fuel and then go to The Fountain for sundaes for a pretty awesome, chill, dinner.
For your shopping list, I'd suggest you stop at a grocery store on your way (if possible.) Not sure how you are arriving, but all car services are fully aware that folks might want to stop for groceries somewhere. All of the ones I have taken ask as soon as you get into the car. But, if not, the Speedway gas station is within walking distance. If you have a rolling suitcase, take a quick stroll over with it, and you will save a few dollars on room foodstuffs.
