Read through this whole thread.. Whew! Thanks for the info, people!
First-time WonderCon attendee from out of town. Looks like most places discussed are $10+ meals, except for Subway (I think this is the closest one: 1770 S Harbor Blvd #136, Anaheim, CA 92802).
Any cheap taco shops within walking range? I'm hoping to spend less on food than on geeky goods. ;-)
Your best bet for tacos will be right out front if there are food trucks. Unfortunately, everything within a few minute walk around the convention center will be overpriced. I think there's a Baja Fresh in the Hilton which will most likely not be the best quality and overpriced--but may be worth not having to walk all over the place. If you are looking for dirt cheap street tacos (probably like $1.25 each), you'll need to walk a looong block or two (~.5 to 1 mile) south of the convention center down Harbor or West st towards Chapman. There will be a ton of hole-in-the-wall Mexican places that way on major corners. Highly recommend tamping down the tourist-y look and walking in a group if going at night. And may not be the cleanest spots.
A couple of other options:
Go with a service like doordash.com and order from farther away restaurants that'll deliver. Get together with 3 or 4 other people to split the extra cost of the deliver fee across multiple people. Honestly you'll probably pay the same amount as you would for the overpriced stuff right around the convention center but the food will be better. I know for me at the end of a long con day, the idea of walking an extra mile or two to find a place to eat is almost unbearable. I haven't stayed at one of the Anaheim convention center hotels because I live nearby, but you could ask the front desk when you check in or call them right now to see how people get food delivered. You probably just need to meet the person in the valet area, but the hotel might let the person just park for a few minutes and they could deliver it straight to a room.
Split the cost of an uber/lyft with a couple of other people and go eat where you want. There are a bunch of pick up/drop off areas in the valets of the hotels near the convention center. There is so much amazing, super cheap food within a 15 minute drive of Disneyland once you get out of the tourist trap.
