Well now, WDW isn't the same as NYC in my opinion. Pricing in some the big cities get pretty crazy, but I accept the challenge! Here are a few I know:
Baltimore is still pretty reasonable. For example: Nacho Mama's -with table service- still gives a free hubcap of chips+salsa per table. Menu has $15 quesadillas, $18.50 fajitas (LARGE portions), and $3.50 soft drinks. Though if you ever go, I highly suggest the crab and shrimp quesadilla at about $25. It has generous LUMPS of premium fresh crab. and we are not talking an ordinary quesadilla. It is a huge fried flour tortilla. Most entrees also come with rice and beans to die for. On top of that, you are surrounded by velvet Elvises and a shrine to native son John Waters. Can easily walk out paying under $20 with leftovers.
DC has California Tortilla where you can get a mean burrito bowl, chips, cheese dip and a large drink for under $15 before tax - $14.88
Detroit/Dearborn Coney Island has dogs for $3-4, with complete fries, dog, drink for $7.80.
Near WDW, PDQ in Winter Garden offers a complete crispy/grilled chicken meal with fries and drink for $9.50 - $11 before tax.
One place on WDW property that offers a great value is Blaze. You can get a generous pie with unlimited toppings and drink for $16 before tax.
Meanwhile, at Universal Orlando's Breadbox you get a sandwich plus side starting at $14, Others are $15-17. The soft drink is $4= so $18-21.
New Minions Cafe meals- including sides- run $13 -$18 ( $18=half rotisserie chicken, fries, and corn on cob), or ramen bowl $19, and drink $4.75. Most meals run $15 plus the $4.75drink. It is semi-table service where you order off electronic menu, and is food delivered to your table. So cute table serve meal for about $20 before tax.
Tampa also has reasonable QS options, inlcuding at least one Sweetgreen, where you get a super high quality salad for $15. They don't offer coke products, and have limited soft drink, but a lemonade is $3.50.- so $18.50.
Now none of these include tax, which adds quite a bit, including 6.5% in the Orlando area.
