@caneinorlando feel free to chime in, this in your wheelhouse.
Go Canes
I'll help out.
I won't mention the good chains on the list (Ruth's Chris, Fogo de Chao, etc.), if you want to hit those, that's fine.
"Convention Area" = International Drive
Del Friscos and Everglades are excellent. I have not been to Mango's, but the current location was designed by an alum of the UM School of Architecture.
"Disney/Lake Buena Vista" = primarily Disney Springs
Just went to Jaleo (Jose Andres' new place) and it was amazing. I took 2 of my UK colleagues, and we tried to get into Morimoto Asia first, but it was a 90 minute wait, so make a reservation 24 hours in advance if you want to do this one. Enzo's Hideaway and Maria & Enzo's are excellent (the Hideaway is downstairs, literally in an old Disney access tunnel).
Downtown - this will be very close to where you will likely go for parking/shuttle to the stadium.
Artisan's Table has been good (I have not been to the new location on Church Street yet). The Boheme is amazing, as always, and Reyes Mezcaleria is a new Mexican place on the north end of Orange Avenue. K and Rusteak are both amazing, but they are located in College Park (northwest of downtown, on the other side of I4). Maxines and Soco are excellent, they are more to the east of downtown (Thornton Park). Bites and Bubbles is good, but it's located in Mills-50 (northeast of downtown, other side of Colonial Drive).
"Restaurant Row" = Sand Lake Road area. Other side of I4 from International Drive, and close to Universal.
Urbain 40 is the obvious choice here, but Pharmacy is the unusual one, it's a speakeasy.
Universal/CityWalk
Not a lot of choices, but Kitchen is solid, it's in the Hard Rock Hotel, downstairs by the pool.
Winter Park - north of downtown
The Ravenous Pig is my personal favorite in the entire bunch. Antonios, Luma, and Prato are all great.
Surrounding areas - probably too far to go
If you want to make the effort, 1921 in Mount Dora is amazing. Chroma in Lake Nona is also very solid, I've been there multiple times.
